How to Profile a Matlab program?

Simple ways

1. To measure the time taken by code, use 'tic and 'toc'.  'toc' gives the time elapsed from last 'tic' command.

timeSoFar = toc; %return the time elapsed from the last 'tic'

2. 'profile on' at the beginning of the program and at the end 'profile viewer' --- This gives detailed information about the time take by each functions.
