Matrix Solver Step by Step App for iPhone and iPad

Detailed Description:

"Matrix Solver Step by Step" Linear Algebra learning tool and a Matrix Calculator:

* Performs most commonly used matrix calculations and decompositions (see list below).
* Demonstrates and explains algorithm steps for almost all the functions.
* Draws interactive geometric references when appropriate.
* Provides explanations and proofs for most Linear Algebra concepts. The proofs have links to all other relevant topics, making them understandable for users with minimal prior knowledge of Linear Algebra.

Every effort is being made to ensure user friendly interface and factual accuracy.
The app is, so far, free of charge and free of ads.
It is being continuously updated with new functions, graphs, and proofs.
Suggestions and corrections are welcome!
