PseudoInverse

• PseudoInverse works on both symbolic and numerical matrices.

• For numerical matrices, PseudoInverse is based on SingularValueDecomposition.

• PseudoInverse[m, Tolerance -> t] specifies that singular values smaller than t times the maximum singular value should be dropped.

• With the default setting Tolerance->Automatic, singular values are dropped when they are less than 100 times , where is Precision[m].

• For non-singular square matrices , the pseudoinverse is equivalent to the standard inverse.

• See Section 3.7.10.
