matlab-engine

I am trying to figure how to use the Matlab engine so I can use C++ GUI with matlab function however I am having some trouble trying to figure out how to use the MATLAB engine classes. The first thing I did was try to run their examples after a bit of trying I go this error upon a successful build, "The application was unable to start correctly 0xc000007b" How do I fix this and will this? In addition I attempted to run my own code too, even though it was simple it still did not work. Note: a did a couple of searches and all I found was that there is a simmilar porblem with adobe cs5, Also I

I'm completely new to MATLAB and I want to know what my options are for data streaming from a C++ file. I heard of using the MATLAB "engine" for this purpose, and some of the methods like engPutVariable, etc., but can someone give me a thorough example of how to go about doing it? I'm trying to implement streaming a sine wave, but a simple example of sending a sample set of data through should suffice. You have two options: the matlab engine and mex functions. It's very important to note that the Matlab API is single-threaded. There is absolutely no way to have user-visible background threads.

I am trying to run the example code from the MATLAB Doc, but when I try to build the project in Visual Studio I get this error fatal error C1083: Cannot open include file: 'engine.h': No such file or directory The fact is that in the Doc I cannot find where to find the header to link it, they show the examples as if there was no need to do anything else, just do the #include "engine.h"; Any ideas about how to solve this issue? EDIT I solved the first problem but now I get some errors reated to missing libs: 1>engwindemo.obj : error LNK2019: unresolved external symbol _engClose referenced in

I open Matlab engine in an initialization thread, doing : bool MY_MATLAB_ENGINE_o::Open() { // Handle the case where engine is already open if( MatlabEngine ) { return true; } else if( !( MatlabEngine = engOpen( 0 ) ) ) { return false; } IsEngineOpen.SetValue( true ); return true; } Function engOpen() opens a COM channel to Matlab. Once the engine is open, the thread falls in wait event mode. Then, in another thread, I do this : bool MY_MATLAB_ENGINE_o::ChangeDirectory( QString strPath ) { QString strPathToScript = "cd('" + strPath + "');"; QByteArray ba = strPathToScript.toLatin1(); const

I'm trying to send simple string commands to the Matlab engine. This is my code (there is no Matlab API related code anywhere else in my code, except for the #include "engine.h" line): void MatlabPlotter::DrawInMatlab() const { std::string PlotCommand = "x=[0 1 2 3 4 5];y=[0 1 4 9 16 25];plot(x, y);"; void * vpDcom = NULL; int iReturnValue; engOpenSingleUse(PlotCommand.c_str(), vpDcom, &iReturnValue); } The code compiles and runs successfully without any compiler errors or run time error messages. The "Matlab Command Window" opens; I get a screen like below: As you see, the command window is

I'm trying to call the Matlab engine programatically from a C program on Linux (Matlab r2009a, Ubuntu 9.10). I've got my own code (which works in Windows), but for now I'm just trying to get the Matlab "engdemo.c" program to work on Linux. I have managed to compile & link it (after including about 15 -l<lib> switches on the gcc command line), and even resolved all the runtime dynamic links via some ldconfig magic. But, when the program runs, I just get the "Can't start MATLAB engine" error message and the program ends, with no indication of why it failed. Has anybody made this work? What have

I am currently working on a project where I need do some steps of processing with legacy Matlab code (using the Matlab engine) and the rest in Python (numpy). I noticed that converting the results from Matlab's matlab.mlarray.double to numpy's numpy.ndarray seems horribly slow. Here is some example code for creating an ndarray with 1000 elements from another ndarray, a list and an mlarray: import timeit setup_range = ("import numpy as np\n" "x = range(1000)") setup_arange = ("import numpy as np\n" "x = np.arange(1000)") setup_matlab = ("import numpy as np\n" "import matlab.engine\n" "eng =
