Thread Subject: MEX basics help ; URGENT !!

I am a newbie to MEX functions.

I took the timestwo.f in the help in Matlab and tried to run
the function but i got the following error.

I also bought a Intel Fortran Compiler 10.1(academic
version). The steps I followed are as follows:

1) Mex- setup

2) the compiler was not in the list (Intel fortran 9.0 was
only there)

3) so I changed the directory when it asked me to verify the
location of the compiler to THE DIRECTORY of FORTRAN 10.1

then after loading the complier (screen output for these
steps are shown below the error portion)

4) when I typed "mex timestwo.f" we got the following error

I really appreciate your help

Thanks,
Charan

It appears that somehow the statement x=2 got put in the middle of the
specification statement. The line should read:

      integer nlhs, nrhs

I am so sorry ...but that was an error in the code...

but the error which shows up now is

//------------error-----------------------------------
>> mex timestwo.f
'link' is not recognized as an internal or external command,
operable program or batch file.
 
  C:\PROGRA~1\MATLAB\R2007B\BIN\MEX.PL: Error: Link of
'timestwo.mexw32' failed.
 
??? Error using ==> mex at 208
Unable to complete successfully.

------------------------------------------------

We think this could be due to the compiler linker...
We are using Intel Visual Fortran 10.1.011

Thanks,
Charan

So it appears that you are fooling MATLAB into thinking it is using
the Intel 9.0 compiler but really pointing it to the 10.1 directory.
That means it is still using the intelf90msvs2003opts.bat file that is
specific to the 9.0 compiler, and probably other 9.0 specific files as
well. I can only wish you luck. I tried something like this in the
past and never was successful. You could try copying the following
files:

    intelf90msvs2003opts.bat
    intelf90engmatopts.bat
    intelf90opts.bat
    intelf90opts.stp

    (or whatever specific 9.0 files that came with your version)

into new files:

    intelf101msvs2003opts.bat
    intelf101engmatopts.bat
    intelf101opts.bat
    intelf101opts.stp

and then hand editing them for the 10.1 specific infomation that you
need. At least MATLAB will find your compiler with the "mex -setup"
command. But like I said, I never got this approach to work so I
can't really give you specifics as to how to modify the files.
Particularly for the linker and linker options. Good luck ...

P.S. If you ever do get this to work I would be interested in knowing
how you did it.

Hi James,

So what is the alternative?

Try another version of Compiler? I will try your steps anyways.

Thanks,
Charan
