DOWNLOAD HERE User Testimonial O.W.: This software is the greatest of the world! User Testimonial A.T.: I must say though, I've been playing with this software for a couple of hours already and it's been great. I really want to thank you infinitely for this. Its made me understand a few things way easier seeing it step by step. Especially since we don't have tutors standing by 24/7 , this is great. I love it a lot. 1) Matrices Enter (Random) Matrices A and B easily (MME has its own Matrix Editor) under F1:, Ideal for Matrix and Vector Classes.
