Moore Penrose Inverse
Overview
The Moore Penrose inverse is defined by
{% A^{\dagger} = (A^T A)^{-1} A^T %}
Equivalence to Inverse
When A is a square and invertible matrix, the Moore-Penrose Inverse is equal to the inverse of the matrix.
This can be seen by deploying the property
{% (AB)^{-1} = B^{-1} A^{-1} %}
