## What is Matrix Solver Step by Step?

“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 tutorials (explanations and proofs) for most Linear Algebra concepts. The tutorial topics 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!

### 5/5 — Great app

*2024-03-05*

This app helps in ways that are ground breaking. Thank you!

**Developer response:** Delighted to hear that our app helped you understand Linear Algebra concepts, and thanks for recognizing this!
We are now working on a new app that has an image editor and demonstrates linear transformations on user created images. It should be released in a month or so. After that, we will come back to Matrix Solver to add step by step explanations for two algorithms
1. Hessenberg Decomposition / Tri-diagonalization.
2. Francis QR algorithm for calculating eigenvalues of Hessenberg / tri-diagonal matrices.

If you have other requests, let us know.
Also, please let us know if you see flaws with the app.

### 4/5 — Good

*2023-12-11*

Took awhile to get the gimmicks of it but it made since once I did

**Developer response:** Thank you for taking your time to figure it out, we are glad you found it useful. Please let us know if you still need any help or if you have suggestions.
Sincerely, Graphmath team
graphmath@aol.com

### 1/5 — Stuck

*2023-11-13*

Stuck on the "New in Version 20.0" screen. Will not allow me to press "Ok" to start the app. Will upgrade review when problem is resolved.

**Developer response:** Jan 2025 update:
We were able to reproduce and fix the issue with app freezing on start.
Better late than never.
-----------------------------
11/24/23: 
We were able to see this issue of freezing on an iPad, however, it was resolved by restarting the device, and there were no further issues. Since we have not heard from you, we are restoring the "New in Version" dialog. Please let us know if the app is working for you.

Sincerely, Graphmath developers

### 5/5 — Excellent app to visualize matrices

*2023-05-21*

Excellent app to visualize and learn matrices

**Developer response:** Thank you!
We still have a long list of future features and UI improvements for the app.
Let us know if you like us to add something to it!

### 5/5 — Not just a calculator, but a learning tool.

*2022-07-09*

Matrix Solver Step By Step places an emphasis on the last part of its name: far from simply providing the answer to common matrix computations, it walks you through a visual angle on the art of matrices and linear algebra. The graphs in this app, like the others from this developer, are powerful, detailed, and highly interactive. 

As a college student who has taken an applied course in linear algebra, downloading this app after the fact allowed me to continue and renew my learning with new perspectives on common matrix techniques.

**Developer response:** Thank you for your review, please check back as we are adding more features to this app.
