The Axis Tool allows the user to make changes quickly to many
items on the axes without refreshing the matrix after each change. It is
especially useful for creating new graphs from scratch or working with large
To open the Axis Tool select Axis | Axis Tool...

Because of the matrix representation, some matrix specific

The diagonalization of a matrix is performed simply. To do
