I made a (free) linear algebra tool - What I use to make my videos

The video tutorial introduces a free tool, Desmos, for handling 2x2 matrices, demonstrating transformations, eigenvalues, and eigenvectors. It covers single input-output transformations, matrix manipulation, and visualizing eigenvectors and eigenvalues, including complex ones. The tutorial aims to provide a practical understanding of these concepts through interactive simulations.

How can users input more coordinates into the program, and what is the outcome of this action?
