This is a question i think fits into L+AA subforum, if not, I do apologise!
I have two n by n matrices, A and B. I need to specify the "number of operations" so I'm thinking (hoping) that will involve some sort of algebraic expression.
I've found so far:-
2x2 = 12 operations
3x3 = 45
4x4 = 112
5x5 = 225
Rubbish. All rubbish. Can anyone help me out?
