A = rand(12000, 400); B = rand(400, 12000); f = @() sum(A.' .* B, 1); timeit(f)
ans = 0.14863What I love about timeit is what it does automatically so I don't have to think about. It warms up the code, decides how many times to repeat the operation, accounts for overhead and determines how long the operation took using statistics. Thank you Steve! Do you have a favorite tip for measuring performance to share?
