Function Svd-Inverse-Slow-Df
(
svd-inverse-slow-df < u > < w > < v > &optional < #:dims > )
Computes the inverse of a matrix that has been decomposed into `u,' `w' and
`v' by singular value decomposition. It assumes the ``small'' elements of `w'
have already been zeroed. It computes the inverse by constructing a diagonal
matrix `w2' from `w' (which is just a vector of the diagonal elements, and then
explicitly multiplying u^t w2 and v. Note that if you are computing the inverse
merely to solve one or more systems of equations, you are better off using the
decomposition and backsubstitution routines directly.
