toolboxCompile.m

% Compiles all mex routines that are part of toolbox.
%
% If you get warnings about "omp.h", your compiler may lack default OpenMp
% support (for info about OpenMP see http://en.wikipedia.org/wiki/OpenMP).
% To compile without OpenMP alter code below to 'useOmp(:)=0'; and re-run
% toolboxCompile. Note that this will disable parallelization and make some
% routines (in particular training certain classifier) much slower.
