To run the xMat from MATLAB, it has to be compiled as a MEX file first. From within MATLAB using GCC this can be done with

mex 'COMPFLAGS="$COMPFLAGS -ffree-form -cpp"' -largeArrayDims -DMATLAB_CALLING xmat.f
delete *.mod;

for Linux with GCC or from Windows with Intel compiler similar to

mex 'COMPFLAGS="$COMPFLAGS /free /fpp"' -largeArrayDims -DMATLAB_CALLING xmat.f
delete *.mod;

Please note, that for compilation the macro MATLAB_CALLING has to be defined next to the flags for free format and preprocessing (as shown).

After successfully compiling the xMat to a MEX file, it should be possible to use the xMat from the provided scripts by simply running the scripts in MATLAB.
