I want to do something like:
x = input('value of x:');
y = input('value of y:');
if (x>=y)
...
else
fprintf('undesirable');
% Then I want to return to the beginning and ask for new x and y inputs. Is there a way to do this? Thank you!

This code will work. To separate undesirable with the next one, you can use \n operator which is for new line. One problem with this code is that it will loop for only 10 times. If in 10 times, x does not become >= y, then also the code will exit. You want the loop to go on until its not undesirable. I think while loop would be better.
Try something like this:
x = 1;
y = 10;
while (x < y)
x = input('value of x:');
y = input('value of y:');
if (x < y)
fprintf('undesirable\n');
end
end

Thank you so much!:D
I was even thinking about using
for i=1:inf
to solve the issue you raised, but your while loop just avoids it nicely.
