I have a set of facial features that i have obtained and would like to classify using SVM. I intend to use libsvm package and use MATLAB to carry out the training.I have already read up on SVM by watching the Stanford lecture. But I am not sure how to use libsvm to start.. Need some guidance...

In matlab you can link your matlab code with some programs implemented in c. This a called a mex-file.
However you need to compile them, to make it work.
You can read the readme file to know how to compile them:
Installation
On Unix systems, we recommend using GNU g++ as your compiler and type 'make' to build 'svmtrain.mexglx' and 'svmpredict.mexglx'. Note that we assume your MATLAB is installed in '/usr/local/matlab', if not, please change MATLABDIR in Makefile.
Example: linux> make
To use Octave, type 'make octave':
Example: linux> make octave
On Windows systems, pre-built binary files are already in the directory `..\windows', so no need to conduct installation. Now we include both 32bit binary files and 64bit binary files, but in future releases, we will provide binary files only for 64bit MATLAB on Windows. If you have modified the sources and would like to re-build the package, type 'mex -setup' in MATLAB to choose a compiler for mex first. Then type 'make' to start the installation.
Example:
matlab> mex -setup(ps: MATLAB will show the following messages to setup default compiler.) Please choose your compiler for building external interface (MEX) files: Would you like mex to locate installed compilers [y]/n? y Select a compiler: 1 Microsoft Visual C/C++ version 7.1 in C:\Program Files\Microsoft Visual Studio [0] None Compiler: 1 Please verify your choices: Compiler: Microsoft Visual C/C++ 7.1 Location: C:\Program Files\Microsoft Visual Studio Are these correct?([y]/n): y
