Well i am simulating few things in MATLAB and want to access few mex files. I have compiled one mex file but another one is giving an error. i am compiling the file with visual C++ compiler but it fails. Can any one help to resolve this issue.
Well i have a C file called BCJR.c. i am trying to compile it within MATLAB with the command
mex -largeArrayDims BCJR.c
i am getting the following error
C:\PROGRA~1\MATLAB\R2011A\BIN\MEX.PL: Error: 'BCJR.c' not found.
??? Error using ==> mex at 208
Unable to complete successfully.
Are you sure that file BCJR.c is in your search path?
http://www.mathworks.com/help/matlab/matlab_env/what-is-the-matlab-search-path.html
the file is in search path. i have folders. In one of the folders i have a mexde2bi.c file which is executed during MATLAB, so obviously it can search it . This file called BCJR.c is in another folder called decoder. Either this cant be found or it cant be executed. I am getting the following error while running the simulation
??? Undefined function or method 'BCJR' for input arguments of type 'struct'.
So you've compiled it and now there is a new problem, right?
To be 100% sure that your function is in search path type in MATLAB:
which -all BCJR
Another possibility is that BCJR does not accept Input Argument of type struct. See simple example:
a.b = 1;
sum(a)
It gives similar error, because MATLAB function sum doesn't operate on structures.
I think your current working folder is different than the folder of BCJR.c.
You need to use cd to go into the \decoder directory before you can use the mex to compile the c file.
Otherwise you can add the whole folder including the subfolders into the matlab path, then you can use mex command directly.
I am also getting same error
mex FMReDistSDF_mex.c
C:\PROGRA~1\MATLAB\R2011A\BIN\MEX.PL: Error: 'FMReDistSDF_mex.c' not found.
??? Error using ==> mex at 208

Please anyone can provide me a solution????
