couple of thoughts before I download the file, for which thanks.

re 1.  why can you not simply change the 'generate_matrix' (I think) function,
to fill that matrix with the file values?

re 2. keep the current way of supplying the size, more flexibility; in a file
that could be the dimensions row/line before the data lines.

not sure I follow.
