D.15.11.2 matrixExp

Procedure from library orbitparam.lib (see orbitparam_lib).

Usage:
matrixExp(A); A matrix.

Assume:
A is a nilpotent n x n matrix.
If the characteristic p of the ground field is positive, then n has to be smaller than p.

Return:
matrix, exp(A)

Theory:
We compute the power series, which terminates since A is nilpotent.

Example:
