A generalized inverse is a matrix *\mathbf{A}^-* satisfying *\mathbf{A A^- A} = \mathbf{A}*.

The purpose of this function is mainly to show how the generalized inverse can be computed using Gaussian elimination.

the generalized inverse of `A`

, expressed as fractions if `fractions=TRUE`

, or rounded
