It is very simple what have you tried?

I only know using 'if' conditional function

That is enough. An else would make more sense, but you can use two if statements with opposite conditions. So let me repeat the question: what have you tried?

@Maria: Part of the reason for asking to see what you have tried is that it helps understand how much MATLAB you know, see how close you are to solving the problem, and see how much effort you have put in yourself.
Without knowing those things, we don't know how much help you need, and we might waste a lot of your time and ours.

if num>100
output= num-100
if num<=100
output=0
This is conditional function, but I cannot use conditional function to solve this. Only logical and comparsion or max function

As this is obviously homework, it's not kosher to just provide the answer ... but hint: look at

A > B implies A - B > 0 . Which implies that the maximum of (A-B) and (0) is (A-B).
A < B implies A - B < 0. Which implies that the maximum of (A-B) and (0) is (0).
