Hello all, I am also getting the same problem. The error looks:
??? Error using ==> svmtrain Function "mxGetIr_700" is obsolete in file ".\compat32.cpp", line 282. (64-bit mex files using sparse matrices must be rebuilt with the "-largeArrayDims" option. See the R2006b release notes for more details.)
