Scilab Function

pinv - pseudoinverse

Calling Sequence

pinv(A,[tol])

Parameters

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).
