• No version of Matlab works on MacOS Sierra

  The MathWorks has published a statement recommends do not update until this problem is fixed. Why we still have the same problem with Mac OS, updates every year? MATLAB is a software more used for engineering! (<-this is a very important field of knowledge.) I don't want to even look upward to the other programs that I need! Now, we will all wait to update until this problem is fixed.

• Do not open attachments MATLAB in TextEdit

  I understand how to set type on a Mac applications. However, there is a problem.

  When I receive an email with a ".m" (MATLAB) file, it should open in TextEdit (on a Mac) because this is the app that I put on my machine. I also put types strangers and plain text to open with TextEdit. But Thunderbird opens a copy of the message in another window and includes the ".m" as an attachment file. He seems unaware that the default is set to TextEdit.

  If you open Preferences(or AppMenu/Options/Options)/room detached/Incoming, there's an entry for ".m" content type files for this? If so, delete it by clicking on the drop-down Action, OK, restart TB, double click on (open) a ".m" attachment and set up the application by default for files ".m"; If TextEdit does not appear, click on the dropdown menu 'Open with', other... and locate the TextEdit program.

  On my Windows 7 system, the default text editor is already available as a default program to open attachments ".m", and the attachment is "inline" displayed in plain text.

• New MacBook (12 ", towards 2015/2016) and MATLAB

  Hey everybody,

  does anyone have experience with the new MacBook (2015/2016) and MATLAB?

  I am currently using the MacBook Pro now after 6 years I want to something new, but I'm quite bad if I have to buy Air or the new one (1.3 GHz dual-core Intel Core m7, Turbo Boost up to 3.1 GHz, 8 GB memory SDRAM 1866 MHz LPDDR3, 512 GB PCIe-based embedded flash storage Intel HD Graphics 515).

  I am a student of neuroscience so I use matlab x times per week as well as spss, otherwise its all the usual stuff (office, senseless surfing the internet, average of much netflix etc.). I will still use my Pro, with a new hard drive, but carrying 2kg of Mac around campus is horrible.

  I regret the new 12 '' MacBook?

  Thank you!

  See you soon

  I use the new Macbook and Igor Pro that is similar in the CPU usage and data processing capabilities. I also have a 15 inch MB Pro, which is a pain to lug around... you will be happy with the new Macbook and don't suffer from the "slower" processor if only using MATLAB.

  One thing to keep in mind is that there are only two hearts, then if you don't have any parallel treatment (whether through Matlab or other calculations) they will be slower. If you do not I recommend the Macbook.

• Localhost UDP connection between FCR and Matlab

  Hi all

  I have a question about the connection between Matlab and FCR UDP. My idea is to Exchange data between Matlab and Labview on the same computer.

  So I found the 'UDP Simple' of the FCR 2.0 sample project where periodically a datasample is generated randomly and sent to the remoteport 61557 local host. In the project a 'fractional number of string for transmission' is used for the transmission of data. The receiver of the sample project reads from the same port to receive the datasample.

  Now, I'm interested to read this simple stream from Matlab (just at first), however, it does not work and I'm not sure why. What I do in Matlab is the following (code Matlab)

  delete variables;
  u = udp ('127.0.0.1', 61557); % Of installation UDP Object
  fopen (u); open reading port %
  A = fread (u, 1);  % read an element
  fclose (u);

  With this code, however, I get a timeout by saying: "' WARNING: unsuccessful reading: the amount of data specified has not been returned within the time limit." "

  I'm not sure why this happens, maybe you could help me out here? I guess that the formet serving to VCF is not the same as in Matlab? Maybe the Terminators are not the same?

  See you soon,.

  Hey

  So, regarding the problem actually, I found the solution today. It was not the firewall, but a simple configuration in Matlab seting the UDP port. So the side of Matlab, to change the definition of udp object according to

  u = udp ('127.0.0.1', 'Thelocalport', 61557);

  If you have

  u = udp ('127.0.0.1', 'Thelocalport', 61557);
  fopen (u);

  A = fread (u)

  fclose (u);
  Delete (u);

  Who does the trick and you can read from the port. Then of course you say Matlab that you read from the "LocalPort" x, which I wasn't aware of.

  On the transmitter side, you simply:

  u = udp ('127.0.0.1', 61557);

  fopen (u);

  fwrite (u, '1');

  fclose (u);
  Delete (u);

  Here, you set just the port of transmiting.

  About the format of the data: I used the simple UDP protocol streaming Comms project where a random number is generated as a double, transformed into a string (ASCII values) and transmitted. At the level of the receiver, you get as much the UDP packet with the ASCII values that you must turn if you want to find the number.

  I hope this helps anyone having the same problem.

• Using a neural network with box Toolbox MATLAB in LabView?

  I would like to know how to train a neural network in Matlab and use it in Labview? I know I should be using the MathScript, but as I do once the network formed in matlab is a dull file?

  Hi GringoButzlaff1,

  Well, it's not all MATLAB code/script that can run in LabVIEW using MathScript.

  If there is a function of IP (intellectual property) in the code, that is, any Toolbox MATLAB functions, you won't be able to execute it using the MathScript.

  In fact, you must call the MATLAB script node in your code. This node calls the script software MATLAB server to run scripts written in MATLAB language syntax and are only available for windows.

  Try encoding using the MATLAB script node and tell me if it worked for you.

  Best regards.

• The value of the seed of the generator of random numbers in Matlab node

  Hi all

  I need to use random variables inside a Matlab Labview Commsuite node. I generate with the randn() function. Is it possible to put the seed of the random number generator such as the random numbers are reproducible?

  Hi Steve,.

  You can use randn ('seed', seeds) to initialize the random number generator. The seed must be a positive integer value. For example, randn ('seed', 3). In addition, this seed is global within the entire application. This means that if the randn() function is called MathScript multi-node that could run in parallel, random results are not guaranteed to be the same after you change any part of your code. But you should always get the same results for repeated passages of the same code.

• Eval commands and Matlab num2str

  All,

  I searched all the 12 pages of this forum and this solution is not found.  If this is a repeat, I am sincerely sorry.

  I try to use the MathScript matlab Module "eval" and 'num2str' orders.  For example:

  II = 01:10;
  eval (['w' num2str (ii) ' = ii ;']);])
  end

  The problem is that 1) it says that it will slow down the program (I get only) and 2) it does not seem to run the script.  I'm looking for some 'w' matrices/vectors/scalars as output.

  In addition, as part of the script that I have other variables that I would use as output.  When I try to add them, labview stipulates that: "you must set this variable in the script and then set its data type. I get the output variable: right click--> Add out--> click variable.  Even variables that are not used in the script I want to pass give the same error.

  For example:

  input variables x = y z

  II = 1:x

  eval (['y' num2str (ii) ' = ii ;']);])

  end

  output (by above method) variables will show all three, but even with just passing through "z" I get this same error.

  This error does not appear when I do basic math in the node and pass the unused variables.

  Ideas, suggestions, solutions would be appreciated.  If necessary I can post some of my code; However, I gave the relevant information above.

  Best,

  Hi hykwei,

  Unfortunately, it is not possible to obtain the MATLAB Script nodes to work
  LabVIEW under your current network configuration. So that the
  Node MATLAB Script to work properly, it takes that MATLAB is
  installed on the same machine as LabVIEW. This means that you will need
  either install MATLAB on the local computer on which you apply
  LabVIEW or you need install and use LabVIEW in the same

  but who sends you right to the copy of MATLAB on the network.
  However, I am not aware if it is still an option or how you could go
  on the implementation of this scheme, so if you are interested, I would contact with

• Import MATLAB generated the file ascii in the Analog Waveform Editor

  Hi all

  I tried to create signals by the Analog Waveform Editor. I have some Waveform generated from MATLAB and recorded as ASCII files, following the instructions on this Web page OR, but it did not work properly. For example, if I produce a column to fill with 0.5 and import the file into the analog signal generator, all I get is a huge series of random number. I missed a few steps in the import of the waveform?

  Thank you!!

  Just for your reference, I could almost in half the size of your file just by saving as .hws. Also to answer your last point, you may have issues opening / importing your .txt file because it may have been opened in another program at the same time. Make sure that you have closed it in Notepad or Excel or other programs which may still be locking on the reference.

  Kind regards

• USB-5133, hws file matlab

  Hi all

  I use USB-5133 to measure voltages of both channels simultaneously. For this, I use the NO-SCOPE. The scope record measured as a DJ-file data. I need these files in Matlab, but I can't open them. What would be the easiest way to export and to open these data in Matlab?

  Any help is greatly appreciated!

  Joonas

  I've never used Matlab, this will probably not be able to help much.  However, NEITHER-HWS uses HDF5 1.4.4 version which was released around 2002 or 2003.  The current version of HDF5 is 1.8.5.  I think remember me some problems of compatibility with 1.4.4 but it has been a long time and I don't remember the details.  Hdf5 recorded the version of the writer in the file to allow compatibility downstream, and the HDFView doesn't seem to have a problem with the file (I was able to trace the track without any problem in the Viewer).  You may need to define a compatibility option in your read file.  See your documentation.

  Data, stored as an array of I8s, are one of the two places (there is only one copy of data, but it is related to two places):

  wfm_group0 / vectors / vector0 / data

  wfm_group0 / traces / trace0 / axis / data_vector / data

  The coefficients of the scale for the data are stored in

  wfm_group0 / traces / trace0 / axis / scale_coef

  It is an array of point numbers floating 64-bit with shift first, followed by the scale factor (₀,₁,...).

  Timing information in the attributes of the x axis:

  absolute timestamp - wfm_group0 / traces / trace0 / axis / ref_time

  first point against the benchmark of timestamp - wfm_group0 / traces / trace0 / x axis / start

  vesting period - wfm_group0 / traces / trace0 / x axis / increment

  Good luck.  My apologies for not having more help.

• Choose from several versions of Matlab

  Is currently working with several different versions of Matlab on my workstation and have not been able to find a way to choose the version that opens when I run a Matlab Script.  It is always default to the same version.  Haven't seen an existing thread that addresses this issue.  Any ideas how to point the script server to a specific version of Matlab?    Thank you.

• MATLAB R2007a to Mathscript

  Hello

  I wrote the MATLAB code to produce a square at a certain frequency to 0.01 seconds. The code performs a loop then back to produce a similar squares but at a different frequency and it then concatenates up to the end of the first square. There are 100 these iterations as she founded a square of frequency change that runs for 1 second (or 0.01 * 100). I want this squares with the computer output speakers.

  The code works in MATLAB, but when I copy in the window of Matchscript it does not work. The commands I use seem to be compatible with Mathscript and it seems that the problem happens at the stage of the loop. My MATLAB code is pasted below and I join the LabVIEW VI with my Mathscript window. Could someone please take a look at my code and see if I am missing any common questions? I am a new user of LabVIEW and am not completely familiar with its intricacies.

  DCT,

  Remember that table in MathScript indices are 1-based, so change the for loop statement "for n = 1/100' should do the job.  It can be a little confusing because array indices are based on 0 in native LabVIEW, so you must make sure to add or subtract 1 during the back and forth between LabVIEW code and MathScript code.
