## Description

“Matrix Solver Step by Step” is a Linear Algebra Visual Guide, 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, explains and draws geometric meaning for 2x2 and 3x3 matrices. 4. Transforms matrix into echelon and reduced echelon forms. 5. Solves systems of up to 8 linear equations with 8 variables. Provides parametric solution equations when number of solutions is infinite. 6. Applies a 2x2 matrix to a 2D grid and displays original and transformed images. 7. Applies a 3x3 matrix to a 3D grid and displays original and transformed images. The images can be rotated around Z axis and tilted up or down. 8. Calculates Eigenvalues and Eigenvectors, both real and complex, for 2x2 matrices. 9. Draws real Eigenvectors for 2x2 matrices. Demonstration of transformation / calculation steps is available for all matrix operations and equation system solutions, except Eigenvector and Eigenvalue calculations. 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. More features and UI improvements are coming soon! Provides links to two other apps by same developers: 1. “GraphMath” Graphing Calculator. 2. “Vectors and Planes” (and Spheres and Ellipsoids) 3D Geometry Visual Guide. Developers hope to get feedback from users at graphmath@aol.com.
