Linear Algebra Functions with NAG Support

Many LinearAlgebra package functions use NAG routines to carry out computations.  The use of the NAG routines allows computations to be carried out very quickly.

This worksheet will guide you through techniques to maximize the power and speed of these routines.

When Maple uses hardware floats, it can execute more quickly than when software floats or symbolics are used.  By understanding how Maple decides which algorithm to use, you can ensure that the most efficient approach is used for your data.
