* libsvm installation instructions (summarized and enhanced from libsvm's README file) If you do not own a 32-bit Windows machine, the easiest way may be to find a Windows machine or a linux machine with g++ installed on it (e.g. unix.andrew cluster also has Matlab installed). Otherwise your machine should have g++ and make installed on it. To see if you have g++, try $ g++ --version in a terminal. - 32-bit Windows Simply copy files 'svmpredict.mexwin32' and 'svmtrain.mexw32' to your working directory in Matlab. - 64-bit Windows I'm not sure about these. Let me know if you're having problems. - Linux & Mac OS X with g++ and Make 1. Make sure 'MATLABDIR' in libsvm's Makefile points to the directory where Matlab is installed on your machine (e.g. /Applications/MATLAB74 for OS X). 2. At a terminal, $ make 3. For linux, copy files 'svmpredict.mexglx' and 'svmtrain.mexglx' to your working directory in Matlab. For OS X, copy files 'svmpredict.mexmaci' and 'svmtrain.mexmaci' to your working directory in Matlab. - Linux w/o g++ and make Do these even exist?? - Mac OS X w/o g++ and make You'll need to first install these (comes with OS X installation CDs) and then follow the steps above.
