This is intended to be a useful repository of self-contained linear
algebra routines. Some of the stuff has been stolen from ../Math,
which in turn used the Cephes maths library sources. Some of it was
ported to PDL from the algorithms in _Numerical_Recipes_, but the
original C code should probably be used if the copyrights allow it.
