• Initialize the array 1 d with predetermined values

  Hi all

  I'm pretty new to the comm suite, but I'll have one (probably simple) question about the initialization of a constant matrix of 1 d. Suppose I want to create a constant 1 d of the matrix of size M and I want to boot with some predetermined values. Is there an easy/effective way to do it? Initializing one is rather heavy, especially for the great Mr. also, how can I initialize such constant on a Traget FPGA?

  I've seen that for example for metering screws, it is possible to define a constant flow of data and initialize it with a .cvs file. Is there a similar possibility to initialize a constant matrix of 1 d?

  See you soon,.

  Hi Steve0,

  I found a quick solution and dirty to do this, as there is not a clear method to implement a constant matrix arbitrarily large. You can generate an array, but you prefer, my example is seen below:

  

  Then go to the front, right click on the indicator and select "capture". From there, this table will be available on your range of data to drop as a constant of other VI in this project. You can also do the same with a CSV file by writing your CSV file to a flag and then enter the data to use.

• How re - initialize an array with the new values at run time?

  Hello

  In this application of particluar I want to change the value of a particular index (Ex: 4th move in a 1 d table) and store the changed value (Inremented) in the same index position.

  I wrote a program, can someone tell what I am doing wrong?

  LabVIEW version: 8.6

  Screenshot kindly updated instead of .vi

  Two things.

  First of all:

  You must initialize the table (via the feedback loop).

  Click with the right button on the wire of the array and create constant.  Move the index of item 99.  Initialize element 0.  This thread up to the lower part of the feedback node.

  Second:

  You use an Insert in the table VI, but it's not describe what you try to do.  While he places an element in the position shown is also increases the size of the table.

  This change to a subset of table replace VI.

• Initialize the array, then using a feedback node to replace items

  Hello friends,

  I have a typical problem. I need to store values in a table 1 d with 7 elements. I want to start with a set zero array of items. I then start sending values and indices one by one so that the value is inserted in the table and is stored. My problem is when I start with a zero table, what happens is every time I have send a value that it replaces a zero to the correct index, but does not store this value for the next iteration as the zero table defines the table to zero once again. Changes as well as an item in the table all the time. I won't like that. Once started, I want all my values stored in the corresponding index, unless until a value with the same index overrides. Here is my attempt in jpg format. I tried to insert a table of zero which takes place once in a while loop and then connect the spare in feedback mode Board so that the insertion of elements Dummies happens only once. But I am not able to do. Please help me view inthi

  

  Your image shows that you cannot have a 'next iteration"because there is no point in loop around the code of the replacement array element and the while loop around the table to initialize is useless. You are not clicking on the button "Continuous run" are you? Do not!

  Here's a basic example. You can learn a few basics of LabVIEW by taking some of the tutorials.

  

• initialize the array index

  Hello!

  I'm new to LabView and I am struggling with this problem for a few days...

  I have a 2D x CH spike_time table and on each line (table 1 d), I need to implement logic that requires the ability to dynamically initialize the two indexes.

  To be more clear, if I says each line of the table 2D with CH, it is the logic I should apply on each line:

  i = 0;

  while I<=>

  {j = i + 1;

  While ch (j) AND (i) - ch (j) ch<= inter_spke_interval="" and="" j=""><=>

  {j = j + 1 ;}

  If j - i + 1 > = min_burst_size then save (i, j);
  I have = j;

  }

  What is the best way to apply this logic in labview?

  How can I manipulate the value of the indxes, i and j to initialize as in the code? I tried to use the "Subset of the table" function in order to 'cut' subset of the line from i and j and records the SHIFT to pass again the subset as the loop, but I couldn't a solution anywhere nearby.

  If someone could share some ideas with me or has a similar vi useful, I would be very grateful!

  Thank you very much!

  Hi MG,.

  I already said you can use SHIFT registers to store I and j!

• MathScript NaN initialize the array LV 8.6

  For those of us who bought LV 8.2 - 8.6 Mac OS Suite of Dev, the mathscript module won't boot has a table with NaN.

  It's

  c = Nan (m, n)

  and

  repmat (NaN, m, n)

  are broken.

  The only work around I can find is to replace a number, for example '0 ':

  InT = repmat(0,m,n); InT (= NaN;)

  Would appreciate any other workaround to create an m x n array of NaN.

  Hi wjdwyer,

  This has been fixed in more recent versions of MathScript, but for older versions, another workaround potential that I could meet you multiply nan by a table that already exists (see below). I know that's not ideal, but if all goes well it will at least give you an alternative.

  A = nan * repmat(1,m,n);

• Convert char [] array of IP address

  How can I convert an array of char [] (acquired from the user input text box) to the IP address?  It seems there being no previous discussion about this.

  Question:
  I have to use an intermediate step of dumping the content I want to check in a textbox.  Why is there not a function that works directly on a table of char []?  It seems faster for me.

  Control of intellectual property is designed as a UI control where the user can interactively enter a text to be used as an IP. The instrument limits user input to the characters 'legal' to an IP address (e.g. only numbers and periods are allowed).

  Since the instrument is distributed with the full code, you may want to consider IsIPvalid (char * string) function in the code: the function is not exposed by the instrument, however, you can check the code and finally transfer to your application if you feel it is valid for your application.

• A different function is created instead of the expected (table Index instead of initialize array) Labview - a 8.5

  Hey all,.

  I have a really strange behavior here. I'm using LabView 8.5. I open a white VI and try to use the function "initialize the array.

  No matter where and how I find (using search functions, or by accessing the 7.x-> table-> table initialize function), when I drag and drop it off at my VI, what I get is "Array Index" instead!

  Even when I hover over the icon table inside the palette is initialized, with aid switched on (Ctrl + H), what I see is the help page for table of Index. It's as if somehow the index table replaced function Initialize array entirely, with the exception of the simple icon in the palette...

  I tried to restart Labview and my computer nothing works.

  Someone at - he never experience a similar problem? that means, one different function other than for being created. I have attached a screenshot.

  Thank you

  -Anne Marie

  Thanks for your replies.

  My palette is screwed a bit isn't it? Most likely because the installation I chose a bunch of older versions in favor... and I regret it now.

  Funny enough, during the search in the functions that it only brings me version 7.x of functions of table etc... but I can manually find the standard in my palette, and of course, version 8.5 standard functions seem to work...

  I need to finally do an install of cean, but for now, it's all good!

  Thank you

• Initialization of an array to match another size of array using the formula node.

  I want to get a few different pictures of the same length and constants in the formula node and output a table corresponding to their length after some minor calculations. Another post, I discovered that I can simply initialize the table as such:

  float pp [100];

  The problem is that I find myself with a much bigger picture than what I need. I want to do is something like:

  float [n] pp.;

  where n represents the entry of an array size in the form node or is something like:

  n = sizeOfDim(td0,0);    Here I use a table 1 d

  None of these methods seem to work. How do I initialize my picture 'pp' such that it matches the length of array 1 d of "td0?

  The more likely your initialization externally.  Create an entry named pp and wire td0 inside as well.  Now create an output with the pp even name and it will contain an array of the desired length.  Of course, this assumes that you want to edit all items in pp.  Otherwise, just use initialize the array to create a new table and feed in the length of td0, and whatever default value you want (ie. 0 or NaN).  The blank values will keep this value after the node of the formula.

  For an array of 1 d example [1,2,3,4,5,6], how to duplicate each element 5 times for example, to generate a new table 1 d as [1,1,1,1,1,2,2,2,2,2,3,3,3,3,3,4,4,4,4,4,5,5,5,5,5,6,6,6,6,6]?

  I'll give you the trick as you build your own logic.

• Table to initialize

  Hello

  I would like to know why I get 2,000 appearing in the table instead of 0.000.  I am trying to initialize the array to 0.

  Thank you
  hiNi.

  In particular, the array itself can have a default value (the two 11 xx values currently), but the item itself can also have a default value, which is 2 in your case.

  It is one of the cases why this idea exists and that it would be useful, so (re) - implemented. (Yes, there have been many versions ago). So please vote for it!

  You have several options to "fix" your VI. For example, you can enter 0 into the third element, select that element (not the value or the table!) and the right-click... make active by default. At this point, all greyed items will change as if by magic to zeros greyed. Now, right click on the new item and ' right click... operations on the data... delete. Voila!

• How can I initialize a spelling?

  I have a program for the HP4192A.

  The program can draw XY, but the next plot will be based on the previous ones. So I have to close the program to delete the graphic.

  How can I add a button or switch to initialize the graph, so I don't have to close the program.

  Thank you very much.

  I cleaned the diagram on the EIS VI test.  It is easier to see what's happening this way.

  Comments on the program:

  1. do not the two wires on the connector a for a loop and connect a table via a terminal autoindexing.  Who has the smallest value will determine the number of times that the loop iterates.

  2. it is generally not a good practice to use the table build inside a loop, because it can cause frequent memory reallocations.  Best practice is to initialize the array to the maximum size, it will reach outside the loop and use replace a subset of table inside the loop.

  3 there is nothing wrong with the mixture of nodes and feedback shift registers in a loop, but this can be confusing someone watching the program later as to why. I prefer the register shift, but it's at least partly because I used LV long before that the crux of the feedback has been introduced.

  4. the high passage registry ends up with the same data that the table introduced in the loop of the sequence constructor screw is there a reason why you take it apart and back together again?  Similarly, it is not necessary use table of Index with the Index Entry linked to i, especially since you already got the same table autoindexing.

  5. I consider amending the measure VI HP4192 more far: eliminate feedback nodes and graphs because you perform these functions in the main VI.

  6 use the Negate, rather than multiply by-1.

  I can't save in version 7.1, so I've attached a picture of the block diagram with many of these changes.
