How to search a table?
Hi every1 through this post
I need your help for a prblm as I am facing currently.
I just returned from a data when prompted. There is a table that stores the data. I want to design a code such as the element entered checks from all of the above and send an error message if there is a repeatition or guests to enter new data in the case of no epeatition.
Can search for the function table 1 d or Match string functions can be used? If so can you please explain... If not, which is the solution to this prblm?
Thank you very much for reading this post. Waiting for your answer and solutions... and comments!
You don't seem to do anything with the release of the 1 d array function research. You want to do something else with this info?
The search function will give you the index number of the array element that contains your string. However you added this in the table in the same line, the index number will always be equal to + 1 loop iteration number for.
The URL should be added to the table if it is not there already. As the research table 1 d function returns-1 if the URL is not in the table, you can use a box structure to add the URL to the table in this case or return an error message if anything, but - 1 is out of the 1 d Array search function.
p.s., Ctrl + h to display the context-sensitive help, this will give you specific information of what each function (and its inputs).

I have a signal that I admire from a PXI-5600 and store it in a table. What I want to do is to find the top of the signal (which I did successfully) and then calculate the bandwidth.
What I do now, is to take the peak value and calculate 20 dB, so I use the "search of table 1 d' but I get index - 1. My guess is that this is happening because of this doesnat table contain EXACTLY the calculated value.
Can I search somehow in the table for the values around one calculated? For example; If I calculated the 10.08 value I want to search all between 9, 9 - 10.1.
so I wonder how I can trace these points whith a line between them in my diet already spectrum
How to index a table on multiple sites?
I searched this issue and was not able to find the answer. I understand that it can be done with loops, but I don't know how.
I use the detector of crete vi for frequency domain data collected a VNA (s2p) file. The products contain a table of amplitudes and a table of locations. The problem is that the locations refer to the index of table of amplitude, which is not the same as the frequency. My idea is that I can use this output of the places table to index the frequency to the detected peak frequencies table and then draw these, as well as some analysis data and manipulation on them. Currently, I can do this only by consulting table on the front panel.
The entrance to the peak detector is currently a table 1 d of the scale (what is the problem?).
I also looked at the supply frequency & estimate VI, but this VI seems only exit of scalar data for the largest peak, not exactly what I'm looking for.
Thanks for your help.
You have a second table for the tested frequency? If so, then you are right that you just need to index this table with the indexes by the Ridge detector. Use a loop for. Automatic index to the index, use index in array to get the value of the frequency and autoindex on frequencies.

There are a lot of collective wisdom in the old posts on the forums of these wonderful. However, I cannot understand is how do to search for old messages that are responses to a large number of major issues. Can someone guide me how to search for messages by user name? Just by typing a user name in the search window gives nothing, but I know there are a lot of previous posts there.
Use this link.
Type the user name in the space on the left side.
And I absolutely agree that there are so many smart and knowledgeable people on these forums. I have discovered this link. One of the superstars of the CSA found.
I wish I could do a search for a specific within the page currently displayed in the browser. Is it possible to do this in Firefox?
Research on a page is actually very easy. You can simply press CTRL + F to use the search feature. You should take a look at the article in the Knowledge Base on How to search the contents of the current for text or links page for more information.
Hope this helps!
5.6.1 pages: How to create a table with more than 999 lines?
The table on Pages v5.6.1 line selector is limited 3-digit, as it is in Pages ' 09 v4.3. Either use LibreOffice Writer, who does not have any constraint line on processing tables 3-digit, or any application spreadsheet for top 3-digit row needs.
By the numbers, how do the list tables on the side? It used to be on the side, now it is on the top which is a huge pain.
This changed in the transition from Numbers2.x too 3.x.
Unless you explicitly removed numbers 2.x, it is always installed and usable on your computer. You can locate it in the folder "/ Applications/iWork ' 09.
You should be aware, that numbers 2.x cannot open files saved numbers 3.x - you can export files from Numers3.x back to Numbers2.x by using the item of menu numbers 3.x "file > export to > number ' 09»

I have a fundamental question on labview. I would like to create a table in a loop 'for' in this way:
inside the loop, if a condition named 'A' is true, then I add a new value to the first column of the table. Otherwise, I have create a new column and start adding values in this column when the condition 'A' is checked, etc.
I put an example of a VI when the 'A' condition is "improving the loop + 1 is not divisible by 5" and the values in the tables are to increase the loop + 1. The loop stops when the increment = 25.
In this example, I have a single column with the values [1 2 3 4 6 7 8 9 11 12 13 14 16 17 18 19 21 22 23 24]
while I wish I had a table of 5 columns:
1 6 11 16 21
2 7 12 17 22
3 8 13 18 23
4 9 14 19 24
Note that this is just an example. More generally, the table may contain columns of different lengths.
Thanks for your response
Try to watch this VI I wrote, it takes a 1 d array and puts it into a 2D array based on a threshold. I think it's a pretty good example on how to insert a table of works. I hope it helps
How to empty a table 2D in TestStand? I have a sequence of test configuration with several 1 d and 2D arrays as local variables. At the end of this sequence, the user can choose an option to restart the installation. In this case, I want to clear all the tables, because all are mandatory and may remain empty, as defined by the user. I use the DeleteElements method to empty the table 1 d. There are notes in the help: "this method is only valid for one-dimensional array objects. Use the PropertyObjectType.ArrayDimensions property to change the size of the objects in multidimensional array. »
But PropertyObjectType.ArrayDimensions is read-only.
Thanks in advance.
SetBoundsByStrings("","") => 1 element: Locals.Array2D, Array of Type [0.0] [0.0]

The upper limits must be defined without any number.
Examples NI TDMS - Express write data .vi (time domain), I can build a PDM file with 2 channels (sine and square waveforms) data, which are stored as test.tdms.
Using Express read .vi data (time domain), 2 channels of waveform data are read. How to build a table later? How to separate the 2 channels of data in the tables 1-2 and manipulate the data using table functions?
I want to collect 100 from index100 between channel 0 and their average. I want to take 50 samples from the channel 50 1 index and double each element.
Thank you for your help.
You can perform operations on different channels in the 2D table using the table to index. This will allow you to choose the channel to operate on, then you can perform the operation inside a loop on each element. In the included code snippet, I used a shift register to find the total cumulative values in channel 0 and then divided by the number of samples.
I recommend you read some tutorials LabVIEW and bases of knowledge on topics that are related to yours. These could help a lot.
I hope that my suggestions help,
I'm programming in VBAI but use LV as my Interface of Inspection. The VBAI program will go into a finite loop (x 1000) and the digital indicator with dbl vaule of food in front of the LV Panel if the value double is in order.
In LV, how to build a table (index 0-999) with this stream?
I created a program that displays a graph of intensity, as well as a histogram of the values of intensity on a chip 1024 x 1024 (dimension X - Y). Currently, the program works well, the histogram takes FOREVER to fill but I was wondering if there is a way to increase the speed of everything including all points of data 1024 x 1024 = 1048576. Thank you!
I realize complete the table of pixel by pixel is not the best route, but I'm not sure how to take the 2D table and use the intensity of each (x, y) point in a histogram.
Thanks, to emphasize that I have no need to call the histogram works every time (rookie mistake), but as I said, I'm still not sure how to the 2D table in the histogram.
And I reset the histogram when finished filling because I need to reset to see the changes for when I change (if necessary) camera exposure time. I have also attached my code.
Can anyone tell why search 1 table D function does not work as expected in the attached VI?
The 2 numbers you have are not equal:
Table number is actually: 0.5872335427799636, you can see this by changing the display format.
Its to do with the way the double value is stored on the computer.
I use an array called "equal about" Comparing the figures with a specified decimal:
I have attached the vi "approximately equal to". As said, you can specify the accuracy of the comparison.
