int is_matrix_row_stochastic(const Matrix *M);

DESCRIPTION

This routine checks if a matrix is row stochastic. A row stochastic matrix is a matrix whose rows consist of nonnegative real numbers that sum to one. Note that the matrix does not have to be square; i.e., this routine does not check for right-stochastic-ness.

RETURNS

TRUE if the M is row stochastic and FALSE if not. If M is NULL, this routine returns ERROR.

DISCLAIMER

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