MATLAB measure a function run time

Question

How to print the time of a function in MATLAB

example:

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

whats the syntax?

Answer 1

you can also use the nonsingleton 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 the use of more than one timer. (otherwise you have to ensure exclusive use of tic and toc for one measurement)

Answer 2

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