Hi, I am reading the help documents about how to program matlab and C C++ together and my questions are a little bit general. It seems that are several ways to call matlab in C C++ and another several ways to call C C++ in matlab. Please correct me if I am wrong or missing something when I try to list them. To call matlab code in C C++, are there two methods available? The first one is Matlab engine and the second one is to use MATLAB Compiler mcc to create C or C++ shared libraries from your MATLAB code. To call C C++ in matlab, are there also two methods? The first one is to call funct...

I'm relatively new to the world of Matlab. I want to call my matlab own code from a C/C++ program on a machine with matlab installed. Do I need to compile the matlab code using matlab compiler tool or the matlab engine is enough for this?

Is it possible to read C/C++ code in matlab and the other way around too? Hi, as long as C or C++ are written in text files you can edit them in the matlab editor. To see the special character of C or C++ coding language, in the editor go to menus: file>preferences>Edito/Debugger>language and on popup "Language" select "C/C++". This does not allow you to run the C/C++ code, just to view it i nicer way... regards, chris saneman <asdfsdf@asd.com> wrote in message <frl846 $f8i$2@news.net.uni-c.dk>... > Is it possible to read C/C...

Hello everyone, How do I compile MATLAB M files into a form that can then be called from within the MATLAB interpreter? A roundabout way would seem to be to (somehow) Turn the matlab code into C (I think mcc does this), then compile this C code into MEX format and call that. Is there an easier way? I have the MATLAB compiler, so I just need to know what to do with it to get this to work.

I am working on conversion of .m files to c/c++. I am using the MATLAB compiler version 3.0 and MATLAB version 6.5.1. There seem to be a few functions which do not seem to get converted. The error i got while using functions like TRAIN, NETWORK and INIT (all neural-networks related functions used in the general neural network programs, newpnn.m etc) is The MATLAB compiler does not currently support MATLAB object oriented programming and the functions TRAIN , NETWORK and INIT would produce a run-time error.

Hello, I'm writing an 3D image recognition which sends commands via RS232 to a Robot which moves to the point in 3D. The problem is the serial interface: sending string commands via serial/fprintf is very slow (I really don't know what matlab makes before sending them) in comparison to e.g. Windows hyperterminal. My question is if it is better to execute a dll out of Matlab-code doing the serial things or viceversus writing a program in c++ which uses the matlab-engine ? What could be the fastest way? What are advantages/disadvantages ? Any help would be appreciated. Thanks in advanc...

Well, I know how to do it with just one double, but now i am trying to use more vars and arrays of doubles. thanks to <http://www.mathworks.com/support/solutions/data/1-X1PFC.html> I knew how to call a function from a matlab generated dll. I am using function [bis, ais, isf, nbiq, qformat] = FLT(f0, f1, beta0, beta1, number_of_txfs, ftype), and the bis, ais, f0, f1, beta0, beta1 and ftype are all arrays of doubles. but when i call the function mlfFLT( 5, ref mxais, ref mxbis, ref mxisf, ref mxnbiq, ref mxqformat, mxf0, mxf1, mxbeta0, mxbeta1, mxnumber_of_txfs, mxftype); all the ref v...

Hi. I'm creating a GUI application in Qt4 that will be calling some matlab functions I've compiled into a shared C++ library. In particular, the Matlab code I'm using is primarily for plotting, so these library calls bring up a Matlab figure window. I want to be able to communicate to the Qt application when I click on the figure (for example); I want a) the Qt app to know that the figure was clicked, and b) be able to figure out the location of the clicked point. Is there any way to create a Matlab callback function, MEX'd or otherwise, that can communicate to a calling applic...

Is there a header file or something that will allow me to utilise MatLab function in my C/C++ application? If so, which header file(s) contain the functions that will allow me to find the inverse and determinate of an C/C++ array, and other 'matrix' operations to be performed on two dimensional arrays? (Left divide would be extremely useful too!) Is there something 'special' that needs to be done for the C/C++ application which is using a two dimensional array to be interpreted as a MatLab matrix, or are they treated the same? Where can I learn more about using MatLab ...

Hello. Need some help with the calling of a matlab compiled DLL (C++ under deploytool). The matlab function takes three strings and return a fourth. I know I have to do something like the pasted code below. I am unsure of the correct usage here, since I couldn't find any examples using strings. Is the return and input correct, or is there some 'int nargin' and REF and OUT keywords? I appreciate any help and hints. -Henrik Gundersen [DllImport("mclmcrrt76.dll")] private static extern bool mclInitializeApplication(string options, Int32 count); [DllImport("mclmcrrt76....

All, Can MatLab call a function in a DLL written in C# as easily as calling into a DLL written in C? If so, how? TIA, Bill Bill If I remeber rightly, there are a couple of articles on codeproject.com that cover this. Do a search for Matlab in the C# category and you should find them Ok.

Unfortunately, they all had to do with calling MatLab from C#, not C# from MatLab. Any other thoughts?

Hello, I have a problem calling C code from Matlab. The mex file compilation is ok. When I run the program Matlab (7.3) crashes. Below is the mexFunction code. Any idea is welcome.

Hi all, I am doing a course project. Try to make phone upload some data to server through PHP script and make Matlab read this file (.txt or any file), process, and write a result file on server. After that, my phone can download the result. The key part is that can I use PHP to call matlab function? Or any mechanism I can use to call Matlab through server-end script? My server will be the local hosted server on Mac computer. Also, Matlab is installed on my mac too. Thanks you very much.
