converting c++ code to Matlab code using Matlab 9im working on a project using matlab. i want to use some of the already writen codes in C++. i want to use these codes in my project rather than writing them from scratch. is there some way or a chunk of code that might convert C++ code to matlab code or a ".c" file to ".m" file. please if anyone knows do let me know at the earliest.thanks

MATLAB code to C codeHi all
I read a similar question posted by someone else but my situation is
slightly different.
I am porting some MATLAB code to C code. I need to find a way to read
jpeg images in C just as imread does in MATLAB. The problem is that I
have tried a number of C libraries, but they do not serve my purpose
completely. I want to read simple grayscale jpeg images into unsigned
interger arrays.
Can someone pls shed some light.
Thanks

C code from MATLAB codeHi
I have a complex algorithm that eventually will be encoded in C to
run on a DSP or Controller (e.g. Hitachi SH4). The present MATLAB
implementation under WINDOWS calls advanced standard MATLAB routines
such as fft, matrix factorizations, eigenvalue solvers, fmincon (for
nonlinear optimization subject to nonlinear constraints), and some
number theoretic functions. I figure that the transcription to an
optimized C code requires many months of hard labor. Before I embark
on this adventure, I would like to generate from my MATLAB code (as
easily as possible, i.e. as automatically as possible) ...
Matlab code to C-codeIf I want to generate C-code from m-file not specifically
for embedded target, which tool can I use? As of I know
emlc converts embedded MATALAB code to C-code. Does the
Real-Time Workshop uses emlc? Please any one tell me how
can I convert my m-file (not only embedded m-file) to C-
code.
Hi Naveen,
i don't think you can do this. if you could, TMW would be
giving away the store! you can, however, use the MATLAB
Compiler to generate a DLL that you can call from C. MCC
will generate a little stub that you call. That stub will
call into the MCR (MATLAB Component Runtim...
calling Matlab code from C/C++ codeHi,
I am learning to call Matlab code from C/C++ code. Here are my
questions
(1)are using Matlab engine and converting Matlab code into a C or C++
shared library the only two ways?
(2) what's the difference between these two methods? Advantages and
disadvantages? In what case use which method is better?
Thanks and regards!

M code into programming C code or MATLAB programming codehallo firends,
Can any body help me write this below code into MATLAB object oriented or C code form please?
M=50; % total number of periods. (choose for 1s duration)
f0 = 50; % fundamental AC frequency
T0 = 1/f0; %fundamental AC period
T = M*T0; %Time for M periods (integer M)
N=30; % sample points per period.
dt = T0/N; % Sample at N points per period (integer N > 20)
t = dt*[1:M*N-1]; % Sampling time array
A0=120/2; % amplitude of AC signal. Divide by 2 or maybe sqrt (2) ?
AC=A0*sin(f0*t*2*pi); % create AC signal.

How to transfer matlab codes into visual c++ or c codes?Hi, Folks
I have written some matlab functions (Matlab 6.5), and I want to
change them into visual c++ or c codes then create a visual c++
project to use the generated c++ or c codes.(visual c++ 6.0).
Could anyone give me the full instructions on how to deal with it
because I have met some unresolved external symbol problems when
linking (use visual c++ 6.0).
Have I missed to include some lib files?
Thanks.
Hi,
Suppose you have an M-file mySquare.m:
function y = mySquare(x)
y = x*x ;
You'll create a dll file by using the command:
mcc -t -L C -W lib:mySquarelib -T link:lib mySquare.m...

C/C++ in matlab and matlab in C/C++ ?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...

Replacing a MATLAB code with a C++ codeI made a program which consists of tens of .m files and I found some
parts of this program are making the whole program slow.
I want to replace those time-wasting parts with C++ codes. I think
C++ codes are a bit faster than MATLAB codes. :)
Is this possible? If possible, can anybody teach me how to do this?
(Or, If there's other way to improve the speed, please let me know.)
Thank you.
Kevin.

Yes: use one or more humans to rewrite the code.
If you are looking for automated methods, then it depends upon which
Matlab version you are using, but chances are that if you are using a
Matlab version old enough to be compilable to C then it probably doesn't
support the Neural Network toolbox.
Are you sure you need to convert...
