Replace the subset of table operation

• Replace the subset of table does not not for me

  I have a loop IN which I want to use a 1-d output Boolean of the comparison table.  There is a one-to-one correspondence between the index of the loop AND array index, so the number of loops and the size of the table are the same.  I first tried using the function insert in the table, which worked well, except that the table kept gaining in size.  Once I understood that, I replaced it by the function replace table subset, which seemed more appropriate.  However, this does not work: nothing ever appears in the table.  I tried using numbers instead of Boolean values, as an experiment, but that no longer works.  I am at a loss as to what I'm doing wrong or not understand and would appreciate suggestions.  I have attached a picture of the relevant part of the VI.

  Thank you

  The shift to your table register is so empty and unitialized.  You can't replace an elmenent that does not exist so that the table remains empty.  You must initialize an array before the loop with the appropriate size and he lead the shift register.

• How to replace the subset of table nd with table 1 d to i, j

  Hello

  I am trying to replace a range of values in an array multidimensional, beginning with the cell i, j, both greater than 0, that is to say a square inside the Bay of nD. The new values which replace older ones come from a 1 d table. However, when I provide two indexes to replace table subset block I get a bad wire... I guess it is due to the fact that labview does not know which direction to replace data? Is there a solution to this? I enclose an example vi of what I'm trying to do.

  Thank you very much.

  This should do the same thing without all the extra steps.

• replace the subset of table

  I have a problem that I can't solve.  I have a table of 6 valves that are a def type.  I want to tell those who are on the use of a loop for.  The for loop count is a wiring number of valves that are put to the test.  I expected indicators 1 to 5 to turn it on in the example, but only 5 shows on.  Can you tell me what I am doing wrong?

  I just thought of it, sorry to bother you.  I changed the entry to a shift register tunnel and left the tunnel to exit as last value is always connected to the indicator of the valve.

  Thank you.

  Metzler wrote: I don't think that your diagram without the loop will work - the original valves begin by the status of the led off.  This is part of a machine to States that tests up to six valves.  County of the Terminal loop is used to iterate the loop many times according to the number of valves tested.

  Then use the array to initialize.

  

• Replace the subset of table w/Shift Register too slow for my Application

  This is similar to other posts, but I have not found one that addresses the limitations of an approach of shift register.

  I have a part of an application that I'm turning to 500-1, 000Hz.  The process extracts a block of data from the ADC, and I need to store this data, then collects more of the ADC.

  I've set up what seems to be the bottleneck of the present in the attached .zip file.  When I run the attached code with profiling (see. PNG file), it tells me that it takes on average 3.8ms for the Subvi to run.  At this rate, I can only run around 260 Hz.  I have a Subvi similar to this in my code and the code can run at 1000 Hz without this Subvi, but slows down to about 160 Hz when it is activated.

  Is it possible that I may collect data about 1.7 KB tables and run at the speed I need?  Any input would be appreciated.

  For purposes of reference. Debugging should be disabled on the sub - vi.

  Looking at the code you provided - don't just disable debugging -! you have some other options of "exécution" to reset.

  

  This should speed up the Sub - vi SR will be your friend again!

• Replace several subsets of table

  I have a 1 d table that I want to manipulate.

  I want to replace the n-th element to the nth + j with zero element... and repeat this replacement to an integer multiple of n.

  So, for example if n = 5 and j = 2, beginning with an array of 1s and then manipulation table might look like:

  1,1,1,1,1,0,0,0,1,1,0,0,0,1,1,0,0,0,1,1, etc.

  So n = 5 to n = 7, n = 12, n = 15 n = 17 n = 10... etc is equal to zero.

  I if the value of n and j with controls on the front panel.

  I'm coming from a background of Matlab and slowly get into Labview.

  Appreciate the help!

  I'd appreciate really indications at this point, I solution mathscript work and would really like to know the 'labview solution '.

  As you will see, a LabVIEW solution will be much simpler. The most important part would be to learn more about the shift registers. This is one of the basic tools.

  Here's a very rough draft of 2 minutes. Modify if needed. Of course replace you your real table and allows to get the size of the array size. See how far you get.

  

• Several problems with a simple replacement of the subset of table

  I'm new to LabVIEW and I try to teach me how to use it.  As you can imagine, I'm running into a few barriers.  The code that I'm including embodies many of my problems.  If someone can explain to me how to improve this code, I would be grateful.

  Copy the following code is a simplified version of a more complex code, that I'm writing.  In the simplified code, I have a control ('VALUE') that I would like to register at different locations in my table of 5 x 3.  To do this, I tried to make a 5 x 3 constant I could replace it with the value of the control.  The code does not work as expected and this is my specific problems:

  1. I can't initialize the array constant (the one I intend to crush).  I can only initialize the first row.  Based on the help files, I thought I should be able to initialize it by clicking on the boxes in the chart on the block diagram and entering values.  But it doesn't seem to let me do this.  Don't know if there is a special way to open when more than 1 dimension is involved?

  2. my slider controls are intended to establish where in the table to place the element.  But is not no longer works.

  3. I can't understand how properly to a code which has a while loop integrated in a while loop.  Someone recommended using a structure of the event, but as a beginner, I will have trouble to know how I would enact who.  I tried to play with the settings of locking/switching the button stop, but that did not work, either. The problem seems to be that, if I am inside the while loop, the program does not see my stop command.  Is there a way to connect as the stop button works, regardless if I'm inside the another while loop?  If not, is there a way to accomplish what I want in the smallest loop without using a while loop?  If I used a structure of the event, how would I created an 'event' to tell the program to store a new data point in the array?

  Thank you.

  Jessica

  Jessica,

  Also note that in LabVIEW array indices are zero-based.  If the values of the row index can be 0, 1, or 2.  If you want your users to see 1, 2, and 3, then put a function decrement between the terminals of the cursor and the function replace table subset.

• Sudden problem with replacement of subset of table

  Hello

  I was working on my project when suddenly a strange problem appeared.

  I have a graph of intensity with 2 sliders that determine the coordinates of my area of interest. I created a simple solution to get these details and store them in table 1 d (x 0, y0, x 1, y1), hence I take them more later to perform some calculations. Now: it's all working fine and dandy that came out of nowhere share the table stopped storing the coords correctly. I put some sensors and index of the sliders and coordinates the eye to be acquired properly. But, for some reason, the function replace subset table stopped their storage in the appropriate cells. Whenever I move a cursor, its coordinates are now stored in the first two cells of a table. I'm pretty sure that I has not changed anything in the code, so what could be the cause?

  Screenshot attached.

  Oficmajster wrote:

  Yep, I added new cases of events previously: cursor type? It was empty, until he did change and why?

  If you don't the wiring of the table in the new case, the table in the shift register will be transformed into a table empty if running new cases. Once the array is empty, replacement of certain elements will not increase the size of the array, it will remain empty.

  Solution: wire the table across all new cases (if you create tunnels of entry-related, it will be automatically )

• How do you replace the values in a control of the ring?

  Hello

  I have a control of the ring (text values) in Labview 2009 and it is populated by programming with 20 points. The end user selects from the list items or fills with a new item based on a checkbox to add a new item. What I want to do, that's when section 20 is entered and the user selects the check box next to the point 21 to add I want around rap on the first item in the list and crush him. Is this possible and a sample VI would be great demonstrate how this is done. Any help would be greatly appreciated!

  Thanks in advance

  Replace the subset of the table.  You need to keep track of the element to replace in a shift register.  I would also like to keep the list in a shift register to make your life a little easier.

• The queue from table question

  I had a recent application where I wanted to take 100 samples of something then get the RMS of the dara. This is happening in a loop, and until the end of the program. Very basic stuff.

  • Method of the QUEUE:
  • Get queues with max 100 items.
  • Queue data (data arrive on every 50mS).
  • Get the status of the queue when the number of items is 100...
  • ... Empty the queue and get all the items (which of course will be a prison guard) and use the RMS funtion.
  • Repeat

  ---------------------

  • TABLE method:
  • Initialize the array with 100 elements of the DBL 9999.99 (it is a value that can only happen in the data)
  • Insert data in the table to help replace a subset of table
  • When 100 index isn't 9999.99, then...
  • ... Put the table in the RMS function, then re - initialize the full array of the 9999.99
  • Repeat

  My questions are, who should be faster, including better management of memory?

  Thank you!

  Why not just use the RMS PtByPt VI. In this way, you don't need to store data at all? This may require that marginally more calculation, but will require less memory.

  If you insist on the pad, I'd probably go with the table for simplicity. I think you can simplify your system to determine when to treat well. No reason to have all these 9999.99 is here.

• Table 3D: cannot replace the 2D subset?

  Hey guys,.

  I discovered a rather strange event (if any). In debugging my code, I stumbled upon my function replace table subset to find that it was the source of my frustration. Either I don't understand how it works for 3D arrays (I use it a lot for 2D, 1 d) or there is a bug. I have attached a picture of the code examples here. I can't replace a 2D picture into my table 3D. I would like to take a page from the 3D and replace it with a page of update / different. The example image is sure to strongly the oddity.

  Any thoughts?

  Regardless of the size of the input array, the result of the table replace never increase the number of items.  You try to grasp the first page, add a line, then replace the first page.  The result is that the replacement is cropped to the initial first page size, if you have a developed NOP (no operation).  Move the entries in your table to build on it and see what happens.

  You can't replace an item that does not exist in the input array.

• generate the subset of the decimal table to an array of Boolean

  I have a decimal table 1 2 3 4 5 6, and I have a boolean with the same table size 0 1 0 1 1 0.

  How can I retrieve the subset of the decimal table of the corresponding "1" position of the table of Boolean (in this case 5 4 2)?

  The value of the Boolean table are editable (casting either 1 00100), so the size of the array decimal subset is not fixed (1, 4).

  (I assume you mean digital Board. "Décimal" is just a specification of formatting and irrelevant for this)

  Try something like the following (the FALSE case has just wired table in the whole unchanged):

  

  (In case you're dealing with huge paintings, a few performance modifications should be made so that everything goes more in place.)

  (Sorry for the spelling errors, ignore them )

• subset of table truncate the end of the 2d array

  The intention was to make a program that would generate asynchronous several different signals in a buffer.  Then something would consume the buffer - an output daq, and signal processing.  I created a dummy consumption which takes only 1% over the beginning of the buffer.  Whenever the buffer is smaller than the specified size, more signal will be added at the end.

  I ran into a problem where the function of the subset of the Array is truncate the end of the subset sometimes, so I disassembled the program until a congruent portion of the code exists to cause the problem.  It seems to be the use of memory or related allowance.  Maybe I'm doing something that I shouldn't be, but it seems like a bug in labview.  In the block diagram, I have a note that shows a waveform wire that goes to a case statement.  Just remove this thread causes it to work properly as seen by the consistency of the waveform on the front panel.

  I'm using Labview 2014 (without SP1)

  I would be grateful for any ideas.

  To work around the problem, use the copy always at the moment. I'll try to engage someone R & D of LabVIEW to get the last word.

  In any case, it seems unnecessary to carry all these t0 (which is always zero!) and dt (which is always the same. Constantly from waveforms to bays and back just really clutters the code. If dt would be different between the waveforms, you would have a much bigger problem .

  I understand that your actual code is much more complicated and what you show is just the tip of the iceberg lettuce.

  Here is a general overview of execution project ideas.

  • Use 'building the table' (concatenation mode) instead of "insert into array. It's cleaner.
  • Use simpler and easier to read the code to find the size of the table smaller
  • Only use tables. You can define once and dt for all graphs.
  • Use the correct representation for buffer size controls.
  • Don't place unnecessary sequence structures.
  • I don't think that you really need that local variables, the terminal is written often enough (stops you extra copy of the immense tables in memory!)
  • Do not know what is the structure of matter, but I left it in for now.
  • Add conditionally empty bays, just wire the table via unchanged instead.
