Your task is to implement the Fast Fourier transform algorithm, without using builtin MATLAB fft commands e.g. fft, fft2, or hardcoded numeric answers in the test case. The test suite employs regular expression matching to reject such solutions.
Creative hacking attempts are appreciated. While I will update the test case accordingly, I'll send you some MathWorks swag if you're the first to demonstrate a new way to get the Test Suite to pass (maybe a t-shirt or coffee mug, you'll have to try and see :-) Jose', yours is on the way.
