Using Function to test height allowed on ride

Many rides in amusement parks require riders to be a certain minimum height. Assume the minimum height is 48” for a ride. Write and test a function to determine whether the rider is tall enough.

MY CODE:

function [ans] = ride(height)
if (height<48)
   height = 'no';
else
   height = 'yes';
end
    
clear
clc
 
addpath('Library')
 
height = input('Whats your height: ');
 
ans = ride(height);
 
if strcmpi(ans, 'no')
    disp('You cant ride')
elseif strcmpi (ans, 'yes')
    disp('not yet')
end

I had very similar code to a classmate and wondering why it will not work? the error that occurs is "output argument "ans (and maybe others) not assigned during call to "ride"."

just wondering if anyone can help with this?

Payton - where in your function, do you assign the result to ans

function [ans] = ride(height)
if (height<48)
   height = 'no';
else
   height = 'yes';
end

I think that you want to assign 'no' and 'yes' to ans instead of overwriting height. I would consider returning a boolean instead of yes/no strings.
