评论： Michael Doherty 2020-4-23

I am writing a script that would validate a statement. The tasl is to promt the user for the values specified below. For each value entered by the user, use a while loop to validate each value according to below. The statement I am trying to validate is "Number of Subintervals" and the value has to be greater than 1. N>1 where N=subintervals.

This is what I got and it does not work.

N=input('enter a number of subintervals greather than one')
while N>1
    if N<1
        disp('Please enter a number greater than 1')
    end
end

If there is anyway you could help that would be great as I am new to coding.

What should happen when

user enters 0
user enters 2

???

If the user enters 2 the while-loop of your code will loop forever.

If the user enters a number less than one, they should be prompted with a statement to enter a number greater than one. If the user enters a number greater than one, it should leave the loop to continue on to another statement validation.
