Number of loops as array Index

• array index

  Hello

  I built a small VI which displays a table 1 d of the images and a table the values of each image pixel 2D (it becomes 3D). I would like to have access to the array index to view the image with its pixel values (see attachment).

  If there is no way to access the index because it's an exit, I thought about a 2 column table where the first column will be composed of images and the second of all the value of the corresponding pixels 2D paintings. And the display could be done at the same time because it will be part of the same table.

  I don't really know if I can do it. This seems a little strange to build an array of 2D arrays...

  Thanks for your help people. I searched a lot but I've yet to find something similar. I enclose my VI (8.0), the FileInfo.vi becomes just a binary information and I read images all the (320 * 240 * 2) + 1016 bytes (frame size) + size of the header of the frame.

  It seems that Matthew has proposed a solution that looks like it will work (unfortunately, I can't do anything in LabVIEW for the moment because I upset him, and it is essentially suspended... I'm trying to give him a chance to redeem themselves before that I have to abandon the process and lose my other works... ). What I would say to you, is to ignore the idea of how you store the data in the way that you view the data. All you really need to see is a single image and a table 2D pixel values, with a kind of control that allows you to change the image and table 2D display.

  Grrr. Curse you LabVIEW! Who would have thought that you could not put 300 k items in a Listbox and expect it to work... I just killed LabVIEW; at least the automatic recovery tool works.

  So, now that it's the road, I can whip up an example. I have attached a quick example where you can basically copy the block schema and paste it into your vi (just replace table 3 and table of Image controls with the sons of your loop (you can delete the indicators related to these threads).) It is a very simple GUI that allows you to drag the cursor to select an image, and when you do, it will display the appropriate image and a table of pixel values. The node property is here just so that when you run the program, the correct values will appear even before you click on anything.

• references element-by-element array indexing

  Hello

  I have a simple question. How can I go on a references element-by-element array indexing? For example, when you use a reference to cluster, there is a property node called "controls [of] ' what we spend in a loop for. For a normal array, "enable Indexing" is usually automatically active when you enter a loop for. Why did for an array of references, this is not the case? Thanks for the help.

  Up there, you are working with a reference to a photo table.  Down, you work with a table of references to individual image controls.

  Looks like you do more complicated it must be.

  You can use picture to Pixmap function to get the image data.  And just automatically indexing the images come from the matrix of the images.

  

• Averages for number of loops

  Hi all

  I have a code (attached) in which a triangular wave is supposed to a magnetic field of ramp up and down to very low frequency (0.1 Hz or low). Reading (X) vs keithley reading field (Y) represented by two random numbers generators must be taken in synchronization with the triangular wave point by point. I would be very grateful if you could help to achieve the following objectives:

  1. by taking the average for a few cycles. Basically, I would define the number of loops in the outer circle to the loop and the number of sampling inside everything in a loop and then take the average between the loops.

  (Data for data of loop2 +... + loop1) + data to loop n/n

  2. the averages should be written to the text file and at the same time, I hope I always get the full date in the file action.

  Thank you

  Hadi

  Assuming that you want to monitor the data happens, I would like to initialize several arrays, both to keep the x and are data and to keep the number of each 'package '.

  Now, simply add the new data to the existing elements while incrementing the corresponding number. Dividing by the count will give you the way to be represented graphically. Here's a simple rewrite. The "collection must match the size of the field ramp, so it shouldn't be a separate control, I think. Currently, you graph the two random channels. You would you rather them the two graphic vs of the field instead? You want front and back scans averaged individually or must they go to the same average with a half data table?

  You save operation still seems a little convoluted. How do you actually data to be organized in the final file?

  Here is a quick project to help you get started.

• What is the purpose of the function Array Index in the example attached?

  Hello

  I'm fighting with the Array Index function. I found the attached VI on the OR site which was exactly what I wanted to do, but rather than simply accept that it works and use it, I wanted to understand.

  What is the purpose of the function Index of table inside the while loop? If I put a probe on part and on the other, the values are the same, but if I remove the service and connect directly to the > function, I get an error.

  I do not understand the tables but I don't understand what is happening here. Any help would be appreciated gratefully.

  Thanks in advance.

  

  It is just picking the first reading of the table in the waveform.  If it's good enough (I'd take at least the average of N samples), why not cela?

  

• Can I call a function using the array index?

  I defined a table that stores the name of the function, like this:

  var aresetButtonTop:Array = new Array(resetTop1,resetTop2,resetTop3,resetTop4,resetTop5);

  Then I have a button named "btnresetTop" which, once clicked will be called one of the five functions stored in the array (aresetButtonTop) above. Functions are called at runtime depending on certain conditions. I need to figure out how I can call these functions using the array index. I use the following code to call the function. The value of i has already been calculated.

  
  

  btnresetTop.addEventListener (MouseEvent.CLICK, aresetButtonTop [i]);

  After doing this, I get the following error when I click on the button:

  TypeError: Error #2007: parameter listener must be non-null.
  at flash.events::EventDispatcher/addEventListener()
  at gallerytest_fla::MainTimeline/thumbTopClick()

  Note: thumbTopClick() is a function within which all these codes are written.

  I need to know if it is posible in AS3 to call a function name using array index or not. If so, could you afford ehelp me out.

  You can certainly do.

  In your case, it looks like i is out of range. Show your loop.

• How to build a dynamic array index in the attribute 'to' house arrest

  Hi all
  
  I need to generate xml output with the appearance of multiples of the same complex element. The number of items is calculated dynamically. I use bpelx: append to add items, but I'm crashes when I try to assign values to elements using a variable to index items.
  
  How can you dynamically assign an array index variable in the attribute 'to' a copy instruction? I was able to do in the attribute 'from' the copy statement, following the examples indicated in the documentation for the xpath function. But when I use the concept of intermediate variable, I get a compiler error stating that the query attribute must start with ' / '.
  It works fine when I hard code the index in the attribute of "query" in the statement "copy to".
  
  I use 10.3.3 version JDev and 10.3.3.0 PM BPEL version.
  
  Here are the two methods I've tried:
  ----------------------
  < copy >
  < expression = "concat ('/ client: assTestProcessResponse / client: ScreeningComments / client: CommentItem [', bpws:getVariableData('notesCount'),'] / client: CommentText')" / >
  < variable = "queryText" / >
  < / copy >
  < copy >
  < expression = "bpws:getVariableData('noteText')" / >
  < variable = part of the 'outputVariable"="payload ".
  Query = "bpws:getVariableData('queryText')" / >
  < / copy >
  ----------------------
  < copy >
  < expression = "bpws:getVariableData('noteText')" / >
  < variable = part of the 'outputVariable"="payload ".
  Query = "/ client: assTestProcessResponse / client: ScreeningComments / client: CommentItem ["bpws:getVariableData(&quot;notesCount&quot;) " ""] / client: CommentText "/ >
  < / copy >
  
  ----------------------
  
  Has anyone had a similar problem? Please let me know this is doable and how.
  
  Thank you

  Hello

  I don't know if the following solution is what you want, but I'll try to explain how this would work; (o)

  I understand your question, you have a following like the watch of simple structure xml schema:

  The element is a complex type that has as a child element.
  The element can have 1.. * items

  As you explained that you know how to add loose, common is to use an XML Fragment example

  As you can see now there are two elements with the child element

  After the task to assign the variable content looks like:

  After adding the fragment, you can set the value for the for the first content element in the following way:

  The important thing is to know how to point to the correct position within the payload. It works with that part of the query statement

  [position()=1]
  

  or you can of course use the short version

  [1]
  

  The next task is to dynamically create the reference to the position. Therefore, you can for example use a variable. You can for example something like this:

  And the last step is to set the element of content dynamically using the defined variable

  The only thing to use the defined variable is that part of the query:

  [position()=bpws:getVariableData('Position_Variable')]
  

  Finally, the XML Structure should look like this:

  
    
      
        
          
            Content1
          
          
            Content2

• Determine which cluster and the array index element was clicked on table clusters

  Hello

  I'm overload of brain with dynamic events and references and nodes of property etc.

  I am trying to identify the cluster and the array index element that was clicked on table clusters

  This gives me the name of the element:

  

  Is this reasonable?  How can I get the index?

  Thank you

  Hello

  Download the VI in this link (also attached).  It gives you the index of the array element that you clicked. Hope this will help you.

• For automatic indexing loop should not index empty array

  Hi guys,.

  I wanted to say in this VI remove empty elements in the table. He worked for table 1 d, but as soon as I gave him a table 2D, for some reason that I was unable to remove empty elements:

  So when I was debugging, I saw at the 3rd row and 4th iteration of line, out of the inside OF the terminal loop index outter loop is [].

  Should not the terminal of the index of the outer loop treat [] as 'skip it '?

  In this case, the tunnel of indexation in the outer loop takes an empty 1-d array and adds it as a line to the 2D table. Because the 2D tables can not be serrated, it fills the remaining elements of the line (all) with the default value. Maybe we could say that an empty array should mean 'add all', but this behavior goes back very far and I don't know what effect this would have. As mentioned, it is easy enough to do what you want with a conditional append in the outer loop.

  I mean what you described certainly applies if [] a something, but in this case it didn't. To prove the point, try something like this:

  

  Check the size of the table. You will find that it is 3,0,0. In other words, you have 3 pages, each with an empty 2D array, which is exactly what builds your code.

  I try to avoid dealing with > 2D paintings and which deals with the cases where they can be empty, so I don't remember the details of why this happens, but IIRC, it follows the rules of the system.

• What is the maximum number of associative array indexes?

  I used
  
  number_type type is the number table
  index by pls_integer;
  number_array number_type;
  
  However. When I,
  
  number_array (2808000301): = 42;
  
  It gives the error of overflow because the index type is pls_integer, and when I change the type index number pls_integer it gives an error.
  
  My question is what can I do to prevent this?

  Polat says:
  But, I mean, I also want to know is there a solution without it?

  Thank you Mr President.

  I don't think that the other options are there...

  But it is unlikely that you will need a digital index as 2808000301.

  The tables are not intended to deal with the enormous amount of data...

• need help in the associative arrays indexed by varchar

  Hi, I wanted to fill an associative array that is indexed by varchar, but I'm confused by incrementing the pointer so that the next lines gets inserted into the next available place.
  sample data:
  type ty_tb_tab_acc is record (account varchar2 (30));
  type ty_tb_indx_acct is table of index ty_tb_tab_acc by varchar2 (35);
  
  cursor sampls_cursor is
  Select an account in sam_tab where the clause goes in here
  
  say that my cursor returns 20 accounts. now, I want these 20 accounts will be inserted in the table associative ty_tb_indx_acct
  How should I buckle and incrment table?
  
  Please share your ideas

  This must be done using SQL. Not the tables or collections or associative arrays.

  SQL is the MOST powerful language, that you have in the Oracle RDBMS. It is faster than PL/SQL, when it comes to crunch data. It is more scalable.

  So why then pull data SQL in PL/SQL (expensive) memory? And then shoot some more SQL data in memory of PL/SQL (expensive)? And then use PL/SQL loop processing to compare the two sets of data?

  SQL can do that very quickly and very efficiently - as it was designed for this specific purpose.

  See the JOIN, INTERSECT , and LESS SQL operations to compare data sets.

• Loop LEDs with index-lens ED for infinite times

  Hi, I am a newbie of Labview here.

  While I am trying to convert characters in infinite loop along the LED strips; say the string "NOR."

  My expected results would be NININININI... and stopped by a Boolean stop button.

  However, I tried hard to find ways to continually feed in the elements indexed 2D boolean to repeat the loops by loops than us producer and etc etc, but nothing helped.

  Hope that someone would be kind enough to help. Thank you!

  A simple increment and Quotient & rest will do the trick for you.  I used the size of matrix in order to quickly get the number of rows being generated.  Then in the loop, use a shift register to keep track of what index to get.  After obtaining the index, add 1 (increment) and get then the rest of the new index and the number of lines.  This will reset the index to 0 after reaching the final index.

  

• using the formula node array index

  Hello

  I'm new to labview...

  I am creating a vi that takes a number n and out the primes from 0 to n (i.e. including 1).

  My approach to do, he uses a formula node, but I can't understand how the table index or for each number first output.

  It seems that my indexing algorithm works very well, but I'm just pushing it into the array as an element.

  It'll will be great if someone could take a look at my vi and give me a hint on how to index properly.

  Thank you

  AA

  your output should be a table and index first use [index]

  also you have to declare the index and Prime]

  

• Implementation of associative array (indexes per Table) in the procedure
