Calculate the Moore-Penrose inverse of

A=[2 3  1 -1]              B=[1 2 3 -1]
  [5 8  0  1]     and        [4 5 6  2]
  [1 2 -2  3]                [7 8 10 7]
                             [2 1 1  6]
Check your result in each case(The Penrose's conditions)

想請問一下"Moore-Penrose inverse"這是什麼?

以及該如何解這題
