I am a newbie to MATLAB. Someone sent me the source code for a
stand-alone C++ program. I don't have a C++ compiler on my computer.
Is there a simple way to compile and run the program with MATLAB?

hello,

you have to use the mathworks's script "mcc", if you want compile your
working. For the version 6.1 i know that we need use only function to
compile; for example mcc -c [-B sgl] myFunMain.m fun2.m fun3.m ... funN.m,
the main function which call others must be in first position for the link.
There are a lot of option to compile, -B sgl (if no error) is used with the
graphic library, and -c is to generate the C compiler.
i hope to help (sorry for my english)

merci, but the command "mcc" isn't recognized by my MATLAB program
(version 7).

i typed "help mcc", and the reply was

mcc.m not found.

any other suggestions?

p.s. vous pouvez m'ecrire en francais. je peux vous comprendre,
j'espere.

MATLAB?

Hi Spike,
you will need to buy the MATLAB compiler, see

Titus,

maybe i have it already(?)among all the other toolboxes i bought.

how can i tell?

spike

Titus,

I checked your link. It's not that I want to compile a MATLAB
program. I have source code for a stand-alone C++ program that I'd
like to run under MATLAB. I don't need to compile the resultant
mixture of MATLAB and C++.

spike

type 'ver'
it should show the matlab version, your license and a list of the installed
toolboxes together with their version.

You need the MATLAB Compiler!

_uli

you need the 'matlab compiler' toolbox to do exactly that. Look for mex
functions on the mathwork website...

thanks, uli. amazing what $500 can buy, isn't it?

spike

Yes, you don't need the MATLAB Compiler. You need a C compiler. Then call
the executable with the ! operator.

how about the C compiler Lcc that is included in MATLAB (i am running
MATLAB on a PC)? i tried it on the example source file yprime.c and
it worked, using the mex command. it didn't however work on the C++
program that someone sent me. there were many errors. that may be the
problem of the source code i received, rather than the C compiler.

how does Lcc compare with commercial C compilers that run under
Windows on a PC?

spike

lcc is a C compiler, not at C++ compiler. C and C++ are two
distinct languages. A C compiler does not compile C++ syntax.

One particularly important issue: In C++ you must use the
qualifier extern "C" in the prototype of functions that are
exported as C functions. Otherwise you will get a linker error.
Thus if you write a C++ MEX file, remember to declare the
main mexFunction like this:

extern "C" void mexFunction(int nlhs, mxArray **plhs,
int nrhs, mxArray **prhs);


You can get several free C and C++ compilers for Windows.
E.g. Microsoft Visual C++ Toolkit (also remeber to download
the Windows Platform SDK), Borland C++ Builder Compiler,
Open Watcom, and MinGW (a Win32-version of GCC). Matlab
should work with any of these compilers.

there is also a c++ example in your matlab directory:
~<MATLAB>\extern\examples\mex

have also a look to the technical-solutions site on www.mathworks.com or to
