Calling MATLAB from a C++ program in Linux

Hi there,

I'm trying to call the MATLAB engine from some C++ which I'm writing. I'm using Debian 6.0.4 64 bit. GCC version is 4.4.5-8.

In order to test out what the built in engine can do, I thought a good place to start would be to compile one of the demos which comes with MATLAB (in this case, engdemo.cpp).

I've install csh and when I call g++ engdemo.cpp, these are the errors I get:

% g++ engdemo.cpp
/tmp/ccD4qsD5.o: In function `main':
engdemo.cpp:(.text+0xa8): undefined reference to `engOpen'
engdemo.cpp:(.text+0xf4): undefined reference to `mxCreateDoubleMatrix'
engdemo.cpp:(.text+0x104): undefined reference to `mxGetPr'
engdemo.cpp:(.text+0x12d): undefined reference to `engPutVariable'
engdemo.cpp:(.text+0x13e): undefined reference to `engEvalString'

engdemo.cpp:(.text+0x24e): undefined reference to `engEvalString'
engdemo.cpp:(.text+0x282): undefined reference to `engGetVariable'
engdemo.cpp:(.text+0x2aa): undefined reference to `mxGetClassName'
engdemo.cpp:(.text+0x2e2): undefined reference to `mxDestroyArray'
engdemo.cpp:(.text+0x2ee): undefined reference to `engClose'
collect2: ld returned 1 exit status

Now there seem to be a number of guides on the internet explaining how to set it up. Some make mention of makefiles, but I haven't implemented one as it doesn't actually explain what to do.

Any help you can provide would be greatly appreciated!

Many thanks!

Call Matlab m-file from Matlab Scrip Node
My problem with matlab script node is related to calling function in matlab.  I created an m-file function that takes an imput temperature (from DAQ) and defines a material property.  My matlab script node doesn't seem to recognize my function.  I have placed the function in the folder the vi is currently located, but it doesn't read it.  How do I get matlab script node to read the functions I create in matlab? Add the directory to matlab path, or call the .m file with it full name ( D:\..... \myfile.m) Let me clarify,   I have pasted my matlab code into the matlab scrip node.   In this code, I have called a subfunction that I have created.   Example k(n)=k_c(T(n)) where k_c is a subfunction I have created.   How do I get my code in the node to sucessfully read the subfunction k_c?       As indicated, you need to add the directory where the .m file containing the function resides to the list of paths that are read in. This is your startup.m file. The other option is to do a "cd" command prior to calling your function to change to the directory where the .m file containing the function resides. Thanks for reiterating the information.  My matlab script node is working properly.  I had never used the "cd" command in matlab.  I always set the working directory when I open the program, and put all the m files into t...

Errors when integrating MatLab code into C# program
Hello, I'm trying to learn how to integrate MatLab code into C#. I'm using Matlab R2010a and Visual Studio 2010. I downloaded the following tutorial and executed the MatLab side of the code: http://www.mathworks.se/matlabcentral/fileexchange/12987 However, when I tried to compile the C# code in visual studio, I got the following error: Could not load file or assembly 'MWArray, Version=2.9.1.0, Culture=neutral, PublicKeyToken=e1d84a0da19db86f' or one of its dependencies. The system cannot find the file specified. A quick google search led me to this page, which instructed me to change the target processor to x86: http://www.mathworks.com/support/solutions/en/data/1-B0JOFC/index.html?solution=1-B0JOFC However, as soon as I did so, I received a new error: System.BadImageFormatException was unhandled Message="Could not load file or assembly 'MWArray, Version=2.0.0.0, Culture=neutral, PublicKeyToken=e1d84a0da19db86f' or one of its dependencies.

Error when calling Matlab engine using C++
I tried to call the Matlab engine (as demonstrated in engwindemo.c) using Visual C++ (VS2008) but kept having random unhandled exceptions occuring. The c++ application that calls the matlab engine needs to load several dll files that are located in "\bin\win32" directory of the matlab folder. This folder is added to the PATH environment variable so that the C compiled applications can find these dll files. The unhandled exceptions were caused because erroneous dll files are loaded. I happen to have installed in my PC the Celoxica / Agility DK design suite for compiling code from MATLAB , C to FPGA. It appears that the Celoxica suite also contains a folder with identical dll filenames (but not identical modules) as the ones required by the Matlab Engine. The Celoxica dll files are also present in the system PATH so when I executed my C++ application, the first dll files to be loaded were from the Celoxica folder and NOT from the Matlab folder. Hence the unpredictable behaviour. So if you have the Celoxica / Agility DK suite installed on the same PC as Matlab, and cannot start the Matlab Engine via VS C++, have the above in mind. I solved this by temporarily removing the conflicting Celoxica folders from the PATH environment variable. OS: Vista 32bit Matlab ver: 7.6.0.324 (R2008a) DK Design Suite: 5.0 ...

Calling R, C, C++, C#, Java, Python, Perl, etc. from a SAS program #2
What about a Perl script calling SAS, R, C++, C# etc. rather than SAS calling these languages? Wouldn't it be easier? What are the pluses / minuses? I'm used to write Perl scripts to pre-process messy data (text mining) and produce summary tables, then feed the clean summary tables to SAS. What do SAS engineers think about this strategy? Anybody has thoughts on this? Feel free to reply on http://www.analyticbridge.com/group/sasandstatisticalprogramming Vincent, Let's look at the process. SAS produces a dataset after a lot of processing. You don't need a 3rd party calling a 3rd to do something. Read a SAS dataset directly using the FREE SAS OleDb driver. Once it is in memory, manipulate to your heart's content and then write it back out to the source you need it to go in. Pluses? Minimal steps reduce the surface area.

VI crashs when calling CIN that calls a Matlab dll by lsb that do casting
The problem: A VI that includes a CIN calls a different DLL that was compiled by Matlab 6.5, using an LSB file that performs type casting for Matlab mxArray type variables. &nbsp; The VI crashs when entering the CIN. It seems the code crashs whenever we attempt to access pointers returned by the Matlab DLL. &nbsp; The same VI with the same LSB and Matlab DLL runs correctly in LabVIEW 7.1.1. The Matlab DLL was compiled via the Matlab MCC command. We also compiled the LSB using LabVIEW 8.5 - Multithreaded DLL + 1 byte alignment, via VC 6.0 - this didn't solve the problem. There are no int64 variables. We tried to remove the complex 128 and float64 variables and change them to float without success. We also compiled the LSB using LabVIEW 8.5 - Singlethreaded* + 1 byte alignment or Debug Singlethreaded + 1 byte alignment - again with no success. &nbsp; I have notice that the lvsbutil.exe from the cintools directory was change in 8.5 comparing his size to 7.1.1 and now it is no longer possible to run it from the command line.

Should I call C from LabVIEW or call LabVIEW from C?
I need to write some software and am trying to choose the best development environment. I currently use Borland C++ Builder to develop most of my software and have also used some LabVIEW occasionally. The new package I need to write has to provide several functions, some of which would be better in C++, some in LabVIEW and I am wondering whether to combine the two. So far, I have had a quick play around and called a very basic piece LabVIEW code, built into a dll, from some C++ code. I am about to try to reverse (create dll in C++ and call from LabVIEW) but would appreciate some advice on the advantages/disadvantages of each method. &nbsp; Restrictions I have: 1. I will (probably) be using some hardware which will be supplied with C++ driver functions only. My interface with this card is the 'heart' of my system and is time-critical. Also, I need to assign a pointer to pass to this card (could I do this in LabVIEW?) 2. I wish to analyse data from the card using FFT and related functions so would ideally use the LabVIEW Sound &amp; Vibration and Order Analysis toolkits. I need to use these in real-time where the data sampling rate is fairly high (frequency analysis to be done on 4 channels at once with each channel sampled at approx 100kHz). &nbsp; To add to this, I would like to be able to create/modify the display screen at run-time - something which I am fine with in C++ but understand is very difficult in LabVIEW (I have only used LabVIEW for relatively...

Matlab and C++ in LABVIEW
dear all! Plz help me out that how can i implement Matlab code in LABVIEW.i am using matlab 7.0 and LABVIEW 7.1. is there any method so that i dont have to change the Matlab code and it runs in LABVIEW. secondly can i run a C++ code in formula node exactly as it&nbsp;runs in C++ compiler thnx for ur time Manzoor manzoor, In version 7 and 7.1, LabVIEW have the "MATLAB Script Node" that allows you to run m-scripts from within LabVIEW. Since you have communication between both products, minimal change (if any) is necessary, but you have to have both produts installed on the same machine for this interface to work. In LabVIEW 8.20,&nbsp;NI introduced the Mathscript node and this requirement is not necessary. Please look into this site: <a href="http://www.ni.com/labview/mathscript.htm" target="_blank">http://www.ni.com/labview/mathscript.htm</a>&nbsp;to learn more about mathscript node. In the formula node, you can use C-like convension to develop your equations. However, you can't use object-oriented programming in there. So, you need to remove the objects from the formula and use stricted types. You should be able to obtain more information in the help of the Formula Node. Hope this helps. ...

Linking C++ with Matlab
Hi, I have two sensors, a pressure sensor and a k-type thermocouple. I'm trying to read them into Matlab so that I can create a stripchart and do some analysis. My plan is to obtain the data using a 'Measurement Computing USB-1208LS'. This instrument comes with some data aquisition software written in C. I'm currently trying to write a C++ project in Visual C++ 2010 Express that allows me to grab the data in Matlab, using the tutorial I downloaded from www.engineering.uiowa.edu/~dip/lecture/C++_with_Matlab.pdf as a guide, although this is for an earlier version of Visual Studio. I got the basic structure to compile, but as soon as I tried using any of the mex functions it would no longer compile and I get the following error message mexFunction.obj : error LNK2019: unresolved external symbol _mxCreateDoubleScalar referenced in function _mexFunction I assume that means that it can't 'see' the mex libraries, but I can't work out why. Up until a week ago I knew nothing about c++, so I'm currently on a very steep learning curve. Are there any obvious things I should be looking for? Would anyone be willing to look over my code and check my settings if I were to email them the project?
