A B C D E F G H I J K L M N O P Q R S T U V W X Y Z overview
The pseudo inverse (Moore-Penrose inverse) $ A^+$ of an $ m\times n$-matrix $ A$ is uniquely determined by the following identities:

  1. $\displaystyle A A^+ A = A $

  2. $\displaystyle A^+ A A^+ = A^+ $

  3. $\displaystyle (A A^+)^{\operatorname t}= A A^+ $

  4. $\displaystyle (A^+ A)^{\operatorname t}= A^+ A\,. $
