Matrix Determinant Calculator play online

Here is the simple, straightforward app that allows you to enter a square matrix of any size, and calculates the determinant. It's like solving the mysteries of the universe, but not as exciting.

This app used L-U decomposition (google it if you're into that sort of thing) to make the calculation more efficient, so you can try to see what's the largest size matrix you can input without the app crashing.
