void matrix_int::set_dimensions ( size_t  new_rows, size_t  new_cols  ) Function that sets the size of a matrix. Parameters: new_rows : Number of rows in the matrix new_cols : Numnber of columns in the matrix Functions is used to set dimensions of a previously defined matrix. Example, M.set_dimensions(10,10) makes M a 10x10 matrix.
