I had planned on changing around the constructors: using Matrix.zero(), Matrix.identity(), and Matrix.random() static methods (instead of module functions), and adding Matrix.rotate(), Matrix.translate(), Matrix.scale() for homogenous 4-matrices and with an optional arg that would make a 3-matrix in special cases. Then I thought I'd add affine_transform() and homogeneous_transform() module methods, which could transform several vectors at once if they are stored in a matrix. But I looked over cgkit's interface, and it is EXACTLY what I wanted. I guess my scientific programming background made me think up too general of an interface. So I've cancelled this linear algebra library. If anyone needs the matrix decompositions, and you can't find them elsewhere, you can always make your own library. I was planning on using the public domain code from: http://math.nist.gov/javanumerics/jama/ ftp://math.nist.gov/pub/Jampack/Jampack/AboutJampack.html - Connelly Barnes __________________________________ Yahoo!
