Orders of MathScript

HI all, I'm quite new to LabVIEW MathScript and have had trouble with the help of the command 'load' in the window MathScript to load the data want to sort the data in each column (4 in total) in a data file. I can do this in Matlab, simply by using the following commands:

x = dlmread ('c:\work\plotdata\plotdata',' ');

sortx = draw (x);

Now the problem I'm having is that when I try to read all the data in my data file in MathScript using the dlmread command, I get the error ' error in the function dlmread in line 1. This function is not defined for the number of parameters you provided. "Using the command 'charge' produces the same error. Each columns are separated from each other by 2 spaces - which is what I've specified as above. Please advise on the appropriate method.

Then, I am trying to sort the data in the columns and am unable to do in mathScript. I have attached a picture of the data file that I am trying to sort. Note that the image data has not yet been resolved. For the guidance of the guru...

Hello

I tried to create a file of test like yours and dlmread can read the data successfully in LabVIEW 8.6. I think your problem is that the file name is not correct. By default, dlmread will read the data of the .dlm file if you do not specify the file extension. As a result, your script should read 'c:\work\plotdata\plotdata.dlm '. You can specify the full name of the file including the file extension or rename your data to .dlm file.

For sortx = (x), if the input x is a matrix, MathScript returns the sortx columns in ascending order. This must be what you expected.

Would you please try again?

  • "print" command in Mathscript recording is not the plots in BMP format!

    Hi guys,.

    I am creating a vi that automatically generates a pdf for my project report. I found a way to record the report directly in pdf format (in other words, I have 'print' my report to a (PDFCreator) Virtual PDF printer that saves the file in a specific folder with the date/time under his name.) "So, this was the first step to make the automatic procedure).

    I'm stuck in the next step, which is adding to the report no graphics bad appearance of labview, but the plots of the victims of the Mathscript.

    Yes, after you have added as input 'a' my data to the mathscript node, I use the following commands:

    Figure

    Plot (a)

    print the image

    Now, what is this sequence is to do a beautiful land of my data and then save it as "image.eps" in the default folder.

    However, the eps format is not at all useful to me because I can't import the plot with the 'Add Image to Report.vi '. This vi supports the formats BMP, GIF, WMF, EMF and JPG only.

    So, I want to save as BMP mathscript plot. It's supposed to be possible, but I have not been able to find a way. Using the command 'Print' for Labview Mathscript 2011 reads as follows:

    http://zone.NI.com/reference/en-XX/help/373123B-01/lvtextmath/msfunc_print/

    Syntax


    print

    Print (a)

    Print (file)

    printing (, file)

    Description


    Print the trace window, or save it in a file in BMP or EPS format. If the trace to save window is a plot of the image or a 3D terrain, the file must be in BMP format. Other types of plots, formats BMP and EPS are supported.

    There is no way for me to choose what format I want, and it automatically selects the eps. If I use the command

    print image.bmp

    It gives me an error. So adding the endpoint .bmp is not the way to go.

    Overall, it is essential for me to export the plot in BMP format (in order to import it into the generation of report), but I can't find a way, althouth it is supposed to work.

    Any ideas?

    Thank you

    PS. I run Labview 2011 SP1

    Hello

    You must use the following command

    Print ('test.bmp')

    Instead of

    print test.bmp

  • MathScript failed to meet

    Hello!

    I am using a node Mathscript in BT 8.5.1, but without success. I get the

    error 'Failure of VI to compile' and the Mathscript is 'marked as main error ".  I have

    used Mathscripts before, but never had these problems. I use Windows XP SP3.

    Everything works fine when I try the example of Labview Mathscript.

    You have a solution for this problem?

    Thanks in advance!

    / Mattias

    Hello Mattias,.

    This looks like a subtle problem.  You have a control located at "affix 2009-04 - 17\Data.ctl.»  Unfortunately, MathScript also uses a control called 'data.ctl.'  LabVIEW will not allow two separate controls with the same name be in memory at the same time.  It seems that your order is already in memory when MathScript starts to load, so it binds to your control instead.  This causes internal errors and signals that the VI cannot be compiled.  The only solution now is to rename your control to something other than "data.ctl."  We work on solving cela and hope to be in a future release.

  • store internal variables in the nodes mathscript/scilab

    Is it possible to store the values of local variables in mathscript node? Maybe have an initialization section where variables are implemented and then later updated. And then something to reset the closure of the vi? Im guessing not, im guessing that we must do the same as labview, pass new releases at the entrances, but it is much more natural in a text based language to do it this way (for me anyway).

    Gordal salvation,

    You can use the backup and loading of orders to store variables for your scripts in a file.  Note that these commands will a warning glyph occur which reduces performance, so what I propose is the following:

  • MathScript - using MatLab code

    There were a number of comments about Mathscript and MatLab throughout the area of web pages, but I wanted to just ask a few pointed questions that likely should be easy to answer so that I can be sure my needs will be met with the add-on MathScript. So now,

    (1) one of my colleagues has some programs written by some of the students is no longer with his lab to be able to pack up and send some of his colleagues in different universities who perform the same research, such as it is. The courage of the LabView programs is in the MatLab code; He MatLab and can run them, but external colleagues likely will not. I guess the Mathscript Module will allow me to:

    ___a) transfer the MatLab Code MatLab lymph nodes MathScript and have the same functionality (it does not appear to be an advanced MatLab functions in there, but it's long makes me not want to re - write in graphical programming LabView)

    ___B) create an exe file of these programs with my Application Builder without the need for MatLab or other processing engine must be installed on the destination computers

    Is this the case?

    (2) one thing I noticed on the code MatLab in these programs is that it seems to be variables that are created in a single node and are then called in another (without linking to them via cables which is what I'd be used to it). Is this standard 'persistence' for the use of MatLab nodes and Mathscript has the same functionality? Never used these so I wasn't sure.

    That's about all. I just wanted to be sure before that I go ahead with this option.

    I took a peek at your code and managed to implement your code with a MathScript window. Only, I've declared the variable in each node and has been able to run the VI. The warning, seen in the image below stating when you use global variables with the MathScript node, your code may run more slowly than normal.

    With respect to the use of the Matlab Script node, I don't know if this would work because this node calls into orders Active X of Matlab, which I'm not too familiar with. The Matlab script node does not have an engine that runs in the background, it is actually calls to Matlab and the user must have Matlab installed on their computers to use the Matlab Script node.

    From what we have discussed, I would like to use the MathScript node for your application so that your end user must only installed LabVIEW runtime engine to run an executable file.

  • Problem with ode45 in Mathscript

    Hello

    I have a model no length (aircraft) in matlab code ".m" and I want to use in labview. I want to see the response of this model and for that I use the Mathscript ode_rk45 command. In Matlab, it works perfectly but in Labview, it takes a long time and at the end he gives you nothing. The model has 2 inputs and 20 outputs so maybe it's very big for mathscript. No idea how I can solve it? Can someone help me? I would appreciate a response. Thank you very much.

    Hi Cris_Ibi_1989,

    I would have thought, given the number of steps and ongoing iterations.  You take 100 steps, based on the size of your stage of 1/10.  The ode_rk45 performs a fourth digital method of Runge-Kutta of order on the equation, which means that each of these steps must be at least four iterations.

    I've seen indications on The Mathworks site that the service can be slow, but it may be down to how function parameters are specified and called by the function itself.

    Let me know if it helps.

    Kind regards

  • mathscript node can work on arrays?

    on the help page Labview titled "Setting up the data type of the script node terminals", there is a line that says "because the MathScript node behaves differently that other nodes in script, you cannot change the data type of input terminals. Instead, if wire you a data type not supported for input on a node MathScript, LabVIEW converts the data type to a supported type or displays a cut wire. If LabVIEW converts the data type, a point constraint appears on the terminal where takes place the conversion. After that wire you an entry to a MathScript node, right-click the input terminal and select Show data of Type from the context menu to see the data type of the entry. »

    I don't understand this.

    I want to do math on arrays / vectors using mathscript. This means that I need input terminals in order to have a table data type.

    Say for example I have A [1 2 3 4 5] = (perhaps from a table of average data for 5 different channels) and say that I want to B = a ^ 2 (using the matlab syntax) - I can do this with a mathscript node?

    If this isn't the case, means that I can't do any math vector/matrix using the mathscript node? given that the whole point of matlab is to work on vectors and matrices, if mathscript node cannot do what it would also be a severe limitation.

    Dave

    Yes, you can use arrays in a MathScript node. Just create an entry on the node, give it a name and a value of table of wire to this entry.

  • Change order number/special character artists

    I would like to know if there is a way to change the order of all the artists that begin with a number or a special character order. Currently, they are all sitting at the bottom of the list of the artist on the ipod (and iTunes) but I would like to have all displays at the top of this list.

    This is the sort order...  I think you would need to change the names of the artists so that they start with something that gets sorted at the top of the list in alphanumeric order.  For example, replace 10,000 Maniacs a_10, 000 Maniacs.

    This is not photo - it is a function of the viewing program (probably the finder) - once the photos are exprted form pictures you can see then in different ways which you control, Photos does not - by the finder you can view by name of son, byt several dates, by file size, etc.

    CAN I change the order on my MacBook Air when my phone is connected (but the changes are not published on my phone)

    Hello, wolfebait!

    Welcome to congratulations on getting a new iPhone and Apple support communities 7.  I see your message that you are having problems changing the order of song into playlists that you created, but it only happens on your new iPhone.  I have several playlists I created myself, and I sometimes have to change the order of songs as well.  I'm happy to help you with this.

    1. Open your music app.
    2. Type library on the bottom left.
    3. Touch Playlists.
    4. Press the Playlist you want to change (it must be one that you have created, as organized playlists cannot be changed).
    5. Press 'Edit' at the top right of your screen.
    6. You should now see red circles 'remove' to the left of each song and three horizontal lines gray right of each song.
    7. Press the grey horizontal lines with your finger and drag the song to the position in the playlist that you want it to be in.
    8. When you have finished editing, type "Done" in the upper right corner.
    9. Your playlist should now be in the new order that you chose!
