using max function without conditional function

how using max function, logical operators and comparison operators to write a code that if a number larger than 100, then return the difference between thwo values, and this number smaller than 100 then return 0.

It is very simple what have you tried?

I only know using 'if' conditional function

[Rik]

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

Answer 1

[Walter Roberson]

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).
