DIY Matrix Calculator

Won’t let a row have anything but integer entries. So you can’t divide a row with 5 and 121 by 5, for example. No way to turn off sound. Not the best interface. Clunky. Big numbers make the matrix distorted.

Pretty good row reduction but I am just trying to multiply matrices together and I couldn’t figure it out. An update to allow other matrix operations would be very helpful.

I like the idea of this DIY calculator, but it’s a huge pain to enter matrices and I’m not even sure how to use it to perform row operations.
