Description (last modified by rbeezer)

Adds three methods to the matrix morphism class:

  1. is_bijective()
  2. is_identity()
  3. inverse()

I did not notice that __invert___ via ~ was available by using tab-completion, which should explain the last one.

If there is a theme, it is better support for compositions of these morphisms.

Depends

  1. #11552

Apply:

  1. trac_11553-matrix-morphisms-additions.patch
