In the problem description, you say "The integers should be chosen from the set 1 to n." However, in your example for a 2x2 matrix, you have a 3 as one of the terms. Am I missing something?
function a = match_rot(n)
The problem says given n and s.
However, only n is provided.
Are we allowed to set s?
Lack of s input solved
Sorry guys. Sloppy problem creation on my part. Unfortunately my signature change will invalidate all the solutions up to this point, but yes it should be match_rot(n,s)
"since rot90(a) matches a in exactly _two_ places" for the example in the problem statement?
Tell me the slope
