int ow_invert_matrix_elements(Matrix *source_mp);
DESCRIPTION
This routine replaces a matrix by its element-wise reciprocal.
RETURNS
NO_ERROR on success, and ERROR on failure, with an error message being
set. This routine fails if any of the matrix elements are too close to
zero.
NOTE
This routine overwrites its input. See invert_matrix_elements(3) for an
alternate routine which does not.

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