Expands decompositions stored in compact form into factors.
expand(x, …)a matrix decomposition.

The expanded decomposition, typically a list of matrix factors.
This is a generic function with special methods for different types
of decompositions, see showMethods(expand) to list them
all.
The LU lu, and the Cholesky
decompositions which have expand methods;
