MATLAB measures the execution time of a function

Question

How to print function time in MATLAB

Example:

%%%TAKE TIME
A = [2 1 3 ; 1 2 5 ;3 5 4 ]
[U,S,V]            = svd(A)
%%%FINISH TIME

What is the syntax?

Answer 1

you can also use non-singular forms of tic and toc :

tStart=tic;
A = [2 1 3 ; 1 2 5 ;3 5 4 ]
[U,S,V]            = svd(A)
tElapsed=toc(tStart);

This allows you to use more than one timer. (otherwise you need to ensure the exclusive use ticand tocfor one measurement)

Answer 2

tic()
A = [2 1 3 ; 1 2 5 ;3 5 4 ]
[U,S,V]            = svd(A)
toc()

Answer 3

If the code has many functions and purposes, you can use the function profilefrom the matlab library. Before running m file write profile in the command window. After completion, check each function and the function of the working hours of the children through the profile report. You can get a detailed explanation with help profile.
