Transpose a table 1 d?

• MathScript transpose a table 1 d?

  Hello

  I had a problem with some Mathscript stuff, but I've found a workaround. Problem now is that I do not understand why the workaround works...

  I put a table of column 1 d in a Mathscript node and without him doing anything out. BUT the output has been transposed. If I get a 2D picture, but always with only the values in the first column, it doesn't. Took me forever to figure this out, but it is not really make sense to me why he would flip the 1 d like that. I tried and I got this:

  'The MathScript node and the node of MATLAB script manage 1 d table entered only online'

  from here: http://zone.ni.com/reference/en-XX/help/371361D-01/lvconcepts/scriptnodes/

  This means that whenever I want to use a table 1 d with Mathscript I have to assume that no matter what happens, it goes immediately to get transformed into a line by Mathscript? Is this a bug or is it on purpose? I have attached a VI to demonstrate it better than I can explain it.

  I use 8.6 btw.

  Thank you.

  Hello

  This behavior is by design.  To understand this better, consider what you wrote: "I put a table of column 1 d in a Mathscript node...". "LabVIEW is not the notion of rank compared to the tables of the column.  You can resize your table T to something and then extend it horizontally.  This only changes the display of the data, not anything with the representation internal.  The help text that reference you also gives the workaround solution to transpose the table once it's in the MathScript node, but as you have discovered, work with 2D arrays will also work around the problem.

  You're right: any table 1 d entering a MathScript node will be treated as a vector of the line.  Yet once, since LabVIEW does not differentiate between the two, we have made the choice to treat incoming arrays as vectors in MathScript.  Treat them as column vectors would be also bad 50% of the time, if unfortunately there is not much we can do until LabVIEW allows you to specify the orientation of the vector.

• Transpose the table 1 d for

  Hello

  It is a very simple question: I have a 1 d table appear as a column. I want it to be a row for reason 'cosmetic '.

  How to do this? (I looked and I couldn't find any simple answer that is installed my simple problem)

  Elliot

  You do not transpose a table 1 d. You can develop a control table 1 d or constant vertically or horizontally. Resize an element, and then resize horizontally.

• TRANSPOSE THE TABLE 1 D TO SEARCH AFTER

  Hello

  What I want to do is table 1 d of transposition (I in a column) to use after the 'Search in 1 table D' function, which works only if the table is linear. I have no change before the table 1 d of origin online. I have to transpose it from column to row. Any idea?

  Thank you

  Sorry,

  I thought I needed the data in a row, but the problem was the precision to find the value with 'Search 1 table D'

  There is not a problem, sorry more time.

  Thank you

• Table 2D to 1 d waveform

  With the help of this function I can take a 2d data table and turns them into an array of 1 d waveform.

  If a table of 7 x 100 would give me 7 waveforms with 100 values of y in each.

  The dt would be the same and the departure time would be the same.

  For some reason when I use the waveform graph it is traced 7 waveforms, but charted only 7 points for each.  It must be drawn however many values there is in each waveform in my example 100.

  Without any data stored in your VI, I can't say how your array is configured.  You use a table of index in parallel on each line.  Maybe you should be indexing on each column.

  In addition, your code could be done easily by using a loop For auto-index using the waveform and table 2-D.  The only thing you need to do is to use transpose the table before the loop For the index on the correct size (columns or rows).

  

• How to find the value max and min for each column in a table 2d?

  How to find the value max and min for each column in a table 2d?

  For example, in the table max/min for the first three columns would be 45/23, 14/10, 80/67.

  Thank you

  Chuck,

  With color on your bars, you should have enough experience to understand this.

  You're a loop in the table already.  Now you just need a function like table Max and min. loop.  And you may need to transpose the table 2D.

• How to table of waveform of input 1 d in the lock with the amplifier

  I have a LabView application that I have to change to include a lock in the amplifier.  The application uses a capture card of data several times to capture a sample of 0.1 s of two signals (one signal, a single reference) in a laboratory test.  Before the measure was made by the base RMS module to record the VRM in the signal, and the reference is ignored.  However, the measures that I am now the scene run many s a lower and so I would use a simple RECS in the kit OR of.

  I am happy (I think) with the configuration of GARLIC but I am struggling to understand the requirement of input data.  It should be an array of 2D, with the identifited of reference signal.  However, the output of the part of the utility that captures the waveform is a table 1 d of waveform.  Could someone advise me on how to convert the table 1 d of waveform in a 2D table suitable for admission to the GARLIC?

  As you may have guessed that I am a newbie to LabView, I try to modify an application designed and assembled by a former colleague, so I'd appreciate simple suggestions!

  TIA.

  You have separated for each signal waveform 1 d arrays, or do you have a 1-d single waveform chart where signals are separate items in the table? If this is the first, you should do something like the code below. If you have a single Bay, then the code would be similar - you could just use a table of unique Index function. You may or may not need to transpose the table 2D. I don't know what waits for the lock in Subvi - channel data by row or column.

  

• Combine two tables 1 d in a 2D array

  Hi all

  Maybe I forget what is obvious, but I can't find a solution to combine two tables 1 d in a 2D array AND (it is the impossible part for me) using the tables columns instead of lines.

  Example:

  Table 1:1, 2, 3, 4

  Table 2:5, 6, 7, 8

  Result: 1, 5

  2, 6

  3, 7

  4, 8

  The 'build array' function seems to add all tables as lines... I guess I could transpose the table, but I want it runs in a Subvi in constructions of different loop and I feel a little uncomfortable with it - I guess one would be left with a completely mixed table. I was maybe blind just to find the right function?

  Cheers, Jessi

  Hi Jessi,

  by default, LV is combining tables in rows. So when you need columns you must transpose the sets or use a different indexing scheme...

• Transpose the timestamp, columns of values in row

  Hello
  
  I have a table with the values of newspaper of some measures. This table Gets an entry each day, with the date time and only one value for each hour. The table model is something like that,
  
  Name_EST | Date | VALH1 | VALH2 | .... | VALH24
  Test | 09/01/2011 00:00:00 | 10.8. 5.4 | .... | 14.2
  
  Where the VALH24 VALH1 represents the value of a measure for each hour (09/01/2011 01:00 to 02/09/2011 00:00:00).
  
  I would like to know if it is possible to transpose this table so that I can have a diferent entry (row) for each hour, like this:
  
  Name_EST (Sami). Date | value
  Test | 09/01/2011 01:00 | 10.8
  Test | 09/01/2011 02:00 | 5.4
  Test | 09/02/2011 00:00:00 | 14.2
  
  I think it's simple to do using a stored procedure, but I would have preferred to make no. using a.

• How to draw columns not lines of the spreadsheet?

  Hello world

  It is probably a fundamental issue; But how do I make a data column of graphical waveform drawn rather than data on line?

  I have a spreadsheetwith 6-columns/channel data with approximately 120 000 lines (file .lvm)... I can convert the 2D table to draw; but this screw with my logic when indexing tables etc...

  Do I have to use the XY Chart and manually bring the plot?

  All responses are greatly appreciated.

  Thank you

  Jack

  If you wire a 2D table in the graph, there is an option to right click on the chart to transpose the table for you.

• Generation of series in multiple channels

  Hi forum, I need to ask a few questions. Any help is appreciated.

  (1) I need help with the generation dynamic series in several channels. Here, we can see how the dynamic data set generated by a single channel. But I can't find anywhere, how to generate several series signals in multiple channels.

  (2) what is the limit for this generation series? I think it depends on the material, but I don't know, what is the limit. My hardware is SMU-6544.

  (3) it is possible to generate different signals in different channels using scripts? and to start the production in these channels at the same time? the example given in the script generation labview is unfortunately only for the generation of a channel.

  Thanks in advance,

  Kind regards

  Yan.

  Hi Yan,

  Produce on several channels with multiple data is difficult without a tool to view the data, or series of each channel bitstream concatenated into a software ADE and transposed before be downloaded into memory.  To make Visual things here, I'll assume that you want to generate a pattern of 3 bits on sample of channels 0, 1 and 2 is 8 wide.  Assume the following models of the series bit for each channel:

  ch 0: 0101 1010

  CH 1: 0000 1111

  CH 2:0100 1101

  So the question now is, how do you load this in the SMU-6544(or any other HSDIO hardware)?  Of the two options, you can use Digital Waveform Editor (NEWS) to create visually and save to a file type HWS then load a DJ using the API HSDIO.  It is the easiest in my opinion.

  The second way is construction examples of data based on a basic example.  I want to say is you take it all binary streams and built a 2D table so that it looks like:

  01011010

  00001111

  01001101

  An array of 3 x 8 and then transpose the table that turns into:

  000

  101

  000

  100

  111

  011

  110

  011

  Here you can see we have 8 lines, each line is a sample, and in the form of U32 read in decimal, you get 0, 5, 0, 4, 7, 3, 6, 3.  That's what you can load into our niHSDIO U32 function write a waveform.  I hope you can see how this translation occurs and how it looks like in terms of load on the jury.  Each sample usually contains data for all channels, where each bit in the U32 is one of the 32 channels available on your device.  So if you want to write a '1' on Channel 5, you would load a value of 0000 0000 0000 0000 0000 0000 0010 0000 in the form of sample, where the 5th bit is 1 and all the other bits 0.  In decimal, you would write '32' value.

  With regard to the limitation of the size of series, if your flow rate is slow enough you can disseminate and make an almost endless stream, but assuming that you are running at the maximum rate, your series of waveform size is limited by the size of your on-board memory.  Since each sample generation is 32-bit, which is 4 bytes for example, if a memory size of 32 MB will correspond to 8MS bitstream series max.

  For any questions or comments are welcome.  Thank you.

• application 2D median filter for images

  I want to use the function of median filter 1 d LabVIEW for application table 2d (image).  Vision doesn't have this feature (or I can't find not [using Vision 8.5]).  I guess I can apply the median filter 1 d through the lines, then transpose the table and apply again to the lines (really columns but now the lines because of the conversion).   Just like the use of the 1-d FFT for 2d FFT.  Is this strategy the correct?

  Thank you

  Don

  That's where - IMAQ NthOrder under treatment: Image filters.

  

  By default, it takes the middle number of a 3 x 3 around each pixel region, but can be set to be the biggest, smallest, or any place in between.  Also the ability to set the size of the filter, although it is a non-linear filter (so why it is not separable as you suggest) the time increases significantly.

• Overload CPU display with waveform graph
