----- How to use the app -----

Creating a new matrix:

1) Select your matrix dimensions and click the Create button
2) Once you have a new matrix, you can input your matrix (Empty cells will count as 0) and press Reduce to bring your matrix into row reduced echelon form
3) To save your matrix, click one of the five save buttons at the bottom

Editing a saved matrix:

1) Select one of the four saved matrix (Default matrix is a 3x3 zero matrix)
2) Edit the elements (There are options to clear all entries, clear all zero entries, or insert the identity matrix)
3) Save as the same matrix or another matrix

Performing matrix calculations:

1) Choose the first matrix to be on the left side of the operation
