Sometimes matrix multiply operations are hard to see and understand. With this small application done in C++ in Qt I try to show how a matrix multiplication of range equal three is done.

This application allow you to "debug" your matrix multiplications step by step until they finish. How to work with it?

- Fill both A and B matrices either using the button or by hand.
- Press step button and check out the new value on the C matrix. The A and B cells computed will be highlighted.
- Continue pressing step button until it finish.

As always, the code is available here. In a near future I'll extend the application to be able to work with other dimensions and real numbers.
