 r2119 this space, all Nx1 vectors will have dimension Mx1. Hence the projection will have dimension MxM where each column is a point in the new space. Also, it assumes that M>N. The opposite problem is added in the functions: process_transposed_problem and projection_transposed()... a point in the new space. \note Currently number of rows, N, must be larger (or equal) than number of columns, M. */ class PCA 3: Calculate eigenvalues according to \n \f$\lambda_{ii} = s_{ii}/N_{rows} \f$ \n 4: Sort eigenvectors (from matrix V) according to descending eigenvalues\n */ void process(void);
