// .dmat is a simple ascii matrix file type, defined as follows. The first line
// is always:
// <#columns> <#rows>
// Then the coefficients of the matrix are given separated by whitespace with
// columns running fastest.
//
// Example:
//   The matrix m = [1 2 3; 4 5 6];
//   corresponds to a .dmat file containing:
//   3 2
//   1 4 2 5 3 6

  // Outputs:
