App Description

“Matrix Solver Step by Step” is created by authors of "GraphMath” and “Vectors and Planes”.

It performs following functions:
1. Multiplies two matrices.
2. Calculates matrix inverse.
3. Calculates matrix determinant.
4. Transforms matrix into echelon and reduced echelon forms.
5. Solves systems of up to 8 linear equations with 8 variables.

Demonstration of transformation / calculation steps is available for all matrix operations and equation system solutions.
Matrices up to 8 by 8 can be entered, as screen size allows.
Most recent matrix entry for particular operation and of specific size is saved between program runs.
Input or output matrices can be saved to clipboard and pasted into other input screens in the app, text files and spreadsheets.

Provides link to two other mathematical apps by same developers:
1. “GraphMath” Graphing Calculator.
2. “Vectors and Planes” (and Spheres and Ellipsoids) 3D Geometry Visual Guide.
