get_random_matrix_col - Gets a random matrix column
SYNOPSIS
#include "m/m_mat_basic.h"

int get_random_matrix_col
(
Vector **vpp,
const Matrix *mp
);
DESCRIPTION
This routine gets a random column from the matrix "mp" and puts it into the
vector pointed to by vpp. If *vpp is NULL, then the vector is created.
If it is the wrong length, then it is resized. Otherwise, the storage is
reused.
RETURNS
If the routine fails (due to storage allocation), then ERROR is returned
with and error message being set. Otherwise the index of the column
selected is returned.
DISCLAIMER
This software is not adequatedly tested. It is recomended that
results are checked independantly where appropriate.
