Functions
void	regina::smithNormalForm (NMatrixInt &matrix)
	Transforms the given integer matrix into Smith normal form.
void	regina::smithNormalForm (NMatrixInt &matrix, NMatrixInt &rowSpaceBasis, NMatrixInt &rowSpaceBasisInv, NMatrixInt &colSpaceBasis, NMatrixInt &colSpaceBasisInv)
	A Smith normal form algorithm that also returns change of basis matrices.

Detailed Description

Provides various complex matrix calculations.

Todo:

Feature (long-term): Add a routine to find the rank of an integer matrix; use this to show the rank of the matching equations.
