    4444     the projection will have dimension MxM where each column is
    45      a point in the new space. Also, it assumes that M>N. The opposite
    46      problem is added in the functions: process_transposed_problem and
    47      projection_transposed()...
     45     a point in the new space.

     48     number of columns, M.
