convert C++ code to M-code

hi,

i want to convert a C++/C code to Matlab code (M-file) and
viceversa, what instructions do i need??

Do you know some simple example that illustrate this?? or
some tutorial in the internet or something about this
topic?? something specific and short if possible

thanks for your help

2 options:

1- Use each set of code in it's native format. From C code, you can
link in the MATLAB engine API and call MATLAB code directly from C.
From MATLAB, you can compile your C/C++ code and call it directly from
MATLAB. Both require intermediate knowledge of C programming. See the
"External Interfaces" section of the MATLAB documentation.

2- Port the code to the other language. There are no simple rules for
this. You simply read and understand the algorithm in one language, and
write the code that does the same thing in the other. Depending on how
complex the code is, when porting from MATLAB to C you might benefit
from the use of a third-party library to help with matrix operations,
such as BLAS/LAPACK, Intel Processing Primitives, or the GNU Scientific
Library. (Google each of these). Or, from C to MATLAB, you can often
simplify things tremendously as MATLAB offers many more standard
functions than the C library.

Good luck,

-Peter

There is no language called C++/C. If your code is C,
conversion to M should be straightforward and will cut down
your line count considerably. If your code is C++, you may
find that converting your classes and/or templates will be
tricky.
