edu.gsu.cs.dmlab.math.LAFunctions

public class LAFunctions
extends Object

This class provides an easy access location for the Basic Linear Algebra Subprograms. Make calls to these functions instead of to the compute functions in the implementing classes, that way we can easily change them at a later date without having to change code that relies on the subprograms.
