4. (4 points) Write a MATLAB program (a2q4.m) that computes and outputs the total number of seconds for an event, given the duration of the event in hours, minutes, and seconds. Use MATLAB's input command in three statement to prompt the user to enter the number of hours, minutes, and seconds. Assign the entered values to the variables, h, m, and s, respectively. As an example, the prompt for the first statement should be "Enter number of hours: 11 From the entered values, compute the total number of seconds and assign the result to a variable named sTotal. Display the total number of seconds in the command window: The total number of seconds is: X where x is the total number of seconds. This value is calculated based on the user input.
