# Linear Algebra

Free App

Rated 3.94/5 (32) —  Free Android application by Arash Gholami

The application is both an Instant and Step By Step Solver.
Step By Step Solver means it shows each step taken to reach the answer(ie. shows the user the algorithm behind it) The application can both Solve a Matrix, and also gives the Inverse of a matrix. More over it shows the determinant.
This application is useful for students and instructors, the ones who want to learn and teach linear algebra.
features:
1) Given a matrix, calculates its row echelon and reduced row echelon form.
2) Given a matrix, calculates its inverse, if it exists, and the determinant.
3) For all the above it shows the algorithm behind it in a meaningful colourful way.
Instructions on how to use the application:
1) In this application we used buttons instead of text input. So to give input you need to tap the button and the value in it will be incremented.
2) When you want to construct a matrix, you have 2 buttons, the 1st one is the number of rows, the second is the number of columns.
3) After you made the matrix with the dimensions you wanted, for giving the matrix inputs, you need to tap on each cell to increment the value in it.
4) To change the incrementation value to something else than one, tap on the text box on top of the matrix and change the number. The number can be negative like -5, rational : 7/3, or 3.2.
5) Make sure that the number you type for the incrementation value text box does not follow any space as well as characters, in other words, it should only be a valid number.

very useful

Z70%

Whoever came up with this is a genius

B70%
by B####:

This app is mostly for those already familiar with Lin.al. who want to make computation easier or double check a result. However, it shows step by step operations for those stuck at a particular stage or you can skip to the end to verify a result. Took a couple minutes of playing around to get the hang of it but this app is quite intuitive and will definitely be a great addition as a problem solver.

Great app

H70%

Good example of what not to do in an app

E70%
by E####:

Just needs to show that one need to tap on the buttons to increment or decrement depending on the value of the incrementor

J70%
by J####:

Ich finde dieses gut, denn es hilft mir mit meinem Kurs. Es ist auch sehr interessant, dass man jeden Schritt sehen kann.

A70%
by A####:

Needs a bit illustration to show how it works. Currently, a user must spend time to be familiar with the app.

F70%

Great app. Easy to use, fun to use. I use it during my tutorials and it saves me a lot of time in class

J70%
by J####:

This app is so useful for students who want to do matrix calculations. I rate it five.

R70%
by R####:

The simplicity of this app is remarkable! Despite its simplicity, it is as productive as you would want it to be. Great app, cannot recommend enough!
