benchmark in matlab

To benchmark in Matlab, there are various ways to measure the execution time of a code. Here are two commonly used methods:

1. Using tic and toc functions:

   main.m
   % start timer
   tic;
   
   % code to be tested
   % ......
   
   % stop timer and get elapsed time
   elapsed_time = toc;
   
   % display elapsed time
   disp(['Elapsed time: ' num2str(elapsed_time) ' seconds']);
   187 chars
   12 lines

   This method is simple and easy to use. However, it may not give precise timing for very short times, and also does not provide insight into which part of the code is the slowest.

2. Using the profiling tool:

   main.m
   % start profile
   profile on
   
   % code to be tested
   % ......
   
   % stop profile
   profile off
   
   % inspect the profiler report
   profview
   125 chars
   12 lines

   This method provides more information about the execution time of each function in the code, and also highlights which part of the code is the slowest. However, it is more complicated to use and may slow down the execution of the code.

Overall, the choice of method depends on the specific testing requirements and the complexity of the code being tested.
