int random_split_matrix_by_rows
(
Matrix **target_1_mpp,
Matrix **target_2_mpp,
const Matrix *source_mp,
double fraction
);
DESCRIPTION
This routine splits the source matrix into two matrices pointed to by
target_1_mpp and target_2_mpp, putting a randomly selected fraction
"fraction" into the first matrix and the rest into the second matrix. If the
matrix pointed to by target_1_mpp or target_2_mpp is NULL, then a matrix of
the appropriate size is created. If it exists, but is the wrong size, then it
is recycled. Otherwise, the storage is recycled. If the source matrix is
NULL, then the target matrices becomes NULL also, and any storage associated
with it is freed.
RETURNS
If the routine fails (due to storage allocation), then ERROR is returned
with and error message being set. Otherwise NO_ERROR is returned.
DISCLAIMER
This software is not adequatedly tested. It is recomended that
results are checked independantly where appropriate.
