I have 2 codes codeOld and codeNew, each contains many methods (i.e. both very complex). I'd like to prove that codeNew is better than codeOld as the former is faster. So I googled it and found the following functions to measure the performance: timeit, tic toc, cputime.
I used tic toc before but people say I should use timeit. But I read in many papers, they measure the performance of a code using cputime. This is confusing me because in this help page: They say cputime can be misleading.
So which one should I use if I want to measure the performance and speed of my code?
Many thanks!

i suggest to use this:
This is good for comparison and also for finding bottlenecks and possobilities for improvement.
