Matrix **target_mpp,
const Matrix *source_mp,
const Vector *vp
);
DESCRIPTION
This routine divides each column of a matrix by a vector. The length of the
vector must match the number of rows in the matrix.
The first argument is a pointer to the target matrix. If the target matrix
itself is null, then a matrix of the appropriate size is created. If the
target matrix is the wrong size, it is resized. Finally, if it is the right
size, then the storage is recycled, as is.
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, or if memory allocation fails. The routine will also fail due to
dimension mismatch, but this is currently treated as a bug (see
set_bug()).
