All I have managed to do is to specify values for matrix A = [2,2;2,2] and B=[3,3;3,3], but I am clueless on how to make an expression, say C^n = A^n+B^n where n is a variable constant and C is a variable matrix. I want to be able to input different values for these, and then have octave go through it and print valid! or invalid!, something like that. Specifically, I'm stuck on how to make an expression and the continous checking bit. Please help!
