New description:
This method serves two purposes:
(a) a convenience for getting singular values and clipping small values to
zero.
(b) a starting point for reasonable quality control on numerical
approximations from CDF matrices. This will make a rank computation easy
(though not fool-proof) and this can be used in other situations as a
consistency check. See #7392.
