Hi. I am new in using MATLAB. I have a thesis about code optimization along with my partner. It was recommended by our adviser to use the software in order t measure the running time of the code. The code is in Java Programming Language. Now, how can I measure the running time of the code using MATLAB?

Hi,

I've coded a function that might help you:

hi; where you want to calculate the time of your code so first you placed tic and toc command in your script.e.g: start tic; code toc

Take a look at the tic and toc functions.

Maybe this article also helps:

@Jay You may consider run time experiment which gives an average of the run time taken.

beginn your script with tic and end it with toc. At the end the Elapsed time is showed in MATLAB in seconds.

Hi Taha,

Is there a way that the elapsed time can be stored as an output? Since I am recording the outputs from matlab to an excel file, i want it to also write the elapsed time as well (instead of manually reading the time and writing it down).
