Helping -largeArrayDims flag find c files

I have created a number of mex files using Microsoft Visual C++ 2008 Express and R2010a. These are all saved in C:\Program Files\MATLAB\R2010a\CEtools which has been added to the path. I then receive the following error message:

??? Error using ==> diagmult Function "mxGetIr_700" is obsolete in file ".\compat32.cpp", line 264. (64-bit mex files using sparse matrices must be rebuilt with the "-largeArrayDims" option. See the R2006b release notes for more details.)

diagmult is one of my C files that has been compiled to the following forms: diagmult.mexa64 diagmult.mexmaci64

I then call

mex -largeArrayDims diagmult.c

and get

C:\PROGRA~1\MATLAB\R2010A\BIN\MEX.PL: Error: 'diagmult.c' not found.

Is diagmult my problem .c file? If so where is MEX.PL looking for this file?

Thanks

You need to set the current directory to the directory where diagmult.c is located. Then try the mex command again.

cdold = cd;
cd('C:\Program Files\MATLAB\R2010a\CEtools');
mex -largeArrayDims diagmult.c
cd(cdold);
