The best tool for testing the performance of MATLAB code is Steve Eddins' timeit function, available here from the MATLAB Central File Exchange. It handles many subtle issues related to benchmarking MATLAB code for you, such as: ensuring that JIT compilation is used by wrapping the benchmarked code in a function warming up the code

Dec 28, 2014 · As a result of this, Matlab has to reallocate memory in each iteration. Reallocating slows things down, and more so the larger those variables are, because Matlab needs to find an ever larger chunk of contiguous memory. This would explain why the program seems to run slower as time passes.
