MatrixPseudoInverse
This block outputs the inverse of a non square input matrix using the SVD (Singular Value Decomposition) operation. When the input is an M-by-N matrix, the output is an N-by-M matrix.

Description
The MatrixPseudoInverse block outputs the inverse of a non square input matrix using the SVD (Singular Value Decomposition) operation.
The input matrix can be either of type Double or type Complex.
When the input is an M-by-N matrix, the output is an N-by-M matrix.
If the SVD of A is: A=USV' then the pseudoinverse X of A is given by: X=VS"U'
where S"(i,j)=1/S(i,j) (if S(i,j) =0), U' and V are respectively the transpose of U and V'.
and we have A*X*A=A and X*A*X=X. Both A*X and X*A are Hermitian matrices.
A warning message is printed if the input is badly scaled or nearly singular.
