thanku for the information. However, if we repeatedly run the code we get different elapsed time each time. Any explanation regarding this will be highly appreciable.

Some minor variation is to be expected. One potential cause of variation is different other processes running at the same time your MATLAB code is running. If you're on Microsoft Windows and Windows Update chooses exactly the time you're running your code to "phone home" for updates that obviously consumes some of the computer's attention, thus potentially making your MATLAB code take longer to run.

You could also do the following:
before1=clock code... etime(clock,before1)
It subtracts the time before from the time after.

First you put tic and entering the code that you are working on it after that toc,
Finaly, create a variable called Elapsed_time = toc
Or, you can just wait and matlab will tell you that elapsed time is (XX seconds)

tic and toc is one way to measure the performance of your code. Other ways include the timeit function and the Profiler.

Write a program that reads the departure time of a train and the arrival time and computes and displays the trip time.
