  • The most comprehensive Linear Algebra APP for calculators.

  • Users have boosted their Linear Algebra knowledge.

  • LAME contains what our Matrix software contains but also covers topics such
    as Linear Transformations, Vectorspaces, Kernel, Spanning Sets, Linear Combinations, Bases, (Column) Subspace (as text), and  finds Orthonormal Bases (via Gram Schmidt), Bases for Row Space, Column Space, Null Space, Nullity, and more.  

  • Step by Step - Gram Schmidt Algorithm

  • Step by Step - Diagonalization

  • Step by Step - Row Echelon Algorithm

  • Step by Step - Find Kernel and Range

  • Step by Step - System of Equations with 1 or 2 Parameters

  • Step by Step - LU Decomposition

  • Ideal for quick review in all Matrix and Linear Algebra classes.

  • Easy to use. Just plug in the matrix/vector and the correct answer shows.


User Testimonial O.W.:

This software is incredible: it allows me to solve any Linear Algebra problem, typically step by step!  Plus:  I can carry the program with me at all times.
