The way we call ros::Duration in C++, I need to call in Matlab. What its equivalent expression in MATLAB?

Rahul - are you referring to the code found here ros::Duration Class Reference? See date and time operations for (perhaps) equivalent functionality in MATLAB.

As given in ros::Duration Class Reference, the duration object is created as:

ros::Duration five_seconds(5.0); //Duration of 5 seconds

A similar object can be created in MATLAB using 'duration' function:

>> d = duration(0,0,5)
d = 
     00:00:05
>> d2 = duration(0,0,4)
d2 = 
     00:00:04
>> d-d2
ans = 
     00:00:01

The duration function here is of form duration(hour, minute, second). Other ways to use duration can be found here:
