RE: Using LIBSVM with Octave on MAC

[Sunny Nanuwa]

Hi Thomas

Thank you very much with the help provided.
Your make2.m file worked and I can use the functions created in C/C++ by LIBSVM 
in octave under MAC.

What does the parameter "-Wp,-DMX_API_VER=0x07030001" do that '-o' can't?

LIBSVM is a library package for support vector machine classifier.

There is a package that is standalone and packages(with extra functions) that 
work with MATLAB/OCTAVE. To use the MATLAB/OCTAVE package requires MATLAB 
version higher than 7.2 - which I don't have, anything lower cannot compile 
C/C++ files easily or at all. Octave is the alternative to use these functions.

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
