Seems matrixMultiplication is still used in default examples that are used when clicking "test" button

Sorry about that. Changed my solution instead of the initial function. It's updated now

you need to update the default method name in the example. You're still using 'matrixMultiplication' instead of 'matrix_mult'

Thanks for the feedback. I've added the Wiki page explaining how it should work. Also, I'm kinda new to Ruby, so I wasn't aware of the function naming convention. That's fixed too :)

I'm intending to contribute a Ruby version (since that's how I did it), but I'm waiting for the fork/pull model to become live.
