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.

  • View A,B,AT, BT , even as Binary or Hexadecimal numbers, etc

  • Perform 30+ Matrix Computations (under F2) such as A+B, A-B, k*A, A*B, B*A, A-1, det(A), Eigenvalues, LU and QR - Factorization, Norm, Trace,  more .

  • Step by Step - Simplex Algorithm.

  • Step by Step - Gaussian Elimination.

  • Step by Step - Find Inverse

  • Step by Step - Find Determinant

  • Step by Step - Row Echelon and Reversal (REF and RREF)

  • Step by Step - Cramer Rule
