Different methods for computing the Moore-Penrose inverse (MPI) matrix are reviewed. For the MPI of a matrix product, four mixed type reverse order laws are established. Some relevant numerical computations are given.
numerical examples, Numerical solutions to overdetermined systems, pseudoinverses, reverse order laws, Pseudoinverses for non-invertible matrices, Theory of matrix inversion and generalized inverses, matrix product, Generalized inverse matrices, Moore-Penrose inverse
