Expands decompositions stored in compact form into factors.

expand(x, …)

a matrix decomposition.

further arguments passed to or from other methods.

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.

showMethods(expand)

The LU lu, and the Cholesky decompositions which have expand methods; facmul.
