COMPLETE QUESTION:

Write a function nexthour that receives one integer argument, which is an hour of the day, and returns the next hour. This assumes a 12-hour clock; so, for example, the next hour after 12 would be 1. Here are two examples of calling this function.

>> fprintf('The next hour will be %d.\n', nexthour(3))

the next hour will be 4

>> fprintf('The next hour will be %d.\n', nexthour(12))

the next hour will be 1

Answer:

The following CODE in MATLAB will accomplish this

>> nexthour = input('Please enter a time here: ');

if (nexthour >= 1) && (nexthour< 12)

nexthour = nexthour+ 1

elseif (nexthour == 12)

nexthour = 1

else

disp('You entered an invalid time')

end

Explanation:

In the Matlab code above, the input function is used to receive a value for time in hours (1-12) next we use the if statement to check that the time entered is between 1 and 11 and add 1 as the next hour, else if the value entered is 12, we assign 1 as the next hour. For every other inputs an error message is displayed.
