Well done

This app has a lot of surprisingly powerful features. The interface is not very intuitive, but with time and a leaning curve it can be overcome, at which point the app's features work beautifully.

Diff Eq Problem

The app crashes when you have repeated eigenvalues.

DO NOT BUY!!!

ABSOLUTELY WORTHLESS...can't even calculate eigenvalues for the simplest of 2x2 matrices

DO NOT BUY THIS APP
Why won't this work?Why won't this work?

Terrible app

Do not waste your money like I did. This app is useless!

Help Crashes

Matrix Lab is not rated well but the it makes it difficult to use the app when the Help System crashes every time you select an item for help, including, how do you enter a matrix which is not readily obvious.

Let's hope that this is fixed soon. Until then, I cannot justify more than two stars. Right now I would suggest going for the HP-48 Emulator apps instead.
