double frobenius_matrix_norm(const Matrix *mp);

DESCRIPTION

This routine calculates the Frobenius norm of a matrix. The Frobenius norm is simply the square root of the sum of the squares of the matrix elements.

RETURNS

The Frobenius norm or a negative number if there is an error (not very likely--currently impossible).

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
