The best to do is to use the "Run and Time" in the "Editor" menu. It shows a complete summary of every function that has been called and the time it has taken.

Run and Time changes the execution time, sometimes a fair amount.

execution time can be found by tic-toc command.place tic; before the first line of code and toc; after the last line of the code
e.g.
tic;
MATLAB code
toc;

Its more powerful to use "now" to get the current time than tic & toc, but it takes a bit more effort.

Are you aware of anything that allows folding of tic/toc ? I found that there are undocumented options for tic and toc but what I exactly want is the following:
tic
% doing something large
tic
function_1();
functionTime_1 = toc;
tic
function_2();
functionTime_2 = toc;
wholeTime = toc;
Currently, in this case I see functionTime_1 and functionTime_2 but I don't see the way to get wholeTime.

now1 = tic();
function_1();
functionTime_1 = toc(now1);
now2 = tic();
function_2();
functionTime_2 = toc(now2);
wholeTime = toc(now1);

Also it is very useful to know the time taken or elapsed in Matlab is reading data from an Excel file, especially for very large number of Excel cells.
tic;
xlsread( );
toc;

Also, you can use the profiler

Profiler will give compile+execution time,so not useful in most applications. timeit seems a good option.
Also you can manually use 'clock' function.

I really like using TimeIt.
