-cputime

-https://www.mathworks.com/matlabcentral/answers/19069-computation-time-calculation

Use cputime at the beginning and at the end and calculate the difference. This gives the computation time. Be careful not to have programs running at the same time and no input output processes.

You can start your code by the command : tic

And finish by : toc

It will gives you the computation time of you programs in seconds

Good luck

timeit() function might be more precise since it calls your function several times and returns the median of the times.

tic toc and cputime both may lead to some error, check this link:

Hey just place 'tic' before your code starts and 'toc' in the end.

Chakit Arora Eneko Ortega Yskandar Hamam Ayoub Ezzaki Ravi Verma, thank you all for your answers.

By using tic toc instraction.

tic

Codes you whant to calculate its execution time

toc

You can also use the Run and Time button. It will run your code and give you a detailed report of all the function calls in your code, how many times they run etc

By adding the "tic" at the beginning of your program and the the "toc" at the end of the program

everybody here mentioned timeit and tic-toc;

Most probably you need to evaluate the execution time because you are suffering from long execution time, and would like to improve that.

Matlab profiler is very useful to determine where or which part of your code is consuming the most time.

aside from tic and toc; you can also use:

start_time = clock;

.

.

.

*run your function*

end_time = clock;

etime(end_time,start_time);
