Just taking a step back.
One seldom needs an inverse matrix. Usually it is some analytic
expression, that has an inverse matrix, which has to be calculated
numerically. Often this expression can be re-written to make use of
QR (and SVD) decomposition. One good example is well documented
in wsolve.m
Sincerely,
Dmitri.
