pinv(G)

NAME
pinv - pseudoinverse

CALLING SEQUENCE
pinv(A,[tol])

PARAMETERS

A   : real or complex matrix

tol : real number

DESCRIPTION
produces a matrix X of the same  dimensions as A' such that:

A*X*A = A, X*A*X = X  and both
A*X and X*A are Hermitian .

The computation is  based  on SVD and  any  singular values
lower than a tolerance are treated   as zero: this  tolerance
is accessed by X=pinv(A,tol).
