C# Class AnimatGuiCtrls.MatrixLibrary.Matrix

Matrix Library .Net v2.0 By Anas Abidi, 2004. The Matrix Library contains Class Matrix which provides many static methods for making various matrix operations on objects derived from the class or on arrays defined as double. The '+','-','*' operators are overloaded to work with the objects derived from the matrix class.
