Hi Sunny,

I don't know what to do with libsvm-mat, however, I downloaded the *zip file 
from somewhere and I quickly created "make2.m" from "make.m"  that I also have 
attached to this email. Copy the file "make2.m" into the same directory where 
"make.m" resides and then call "make2" from Octave.
I didn't have the time to take a look what actually I can do with libsvm-mat so 
can you please give us a short explanation about what this package is useful for?

Thanks,

  Thomas
