Create a function based on some criteria

4 views (last 30 days)
Suppose I want to create a function :
y=x^2 for x>5
x^3 for 0<x<=5
-1 for x<0
How to implement this in matlab without using fucntion?
Can it be done in single statement so that I can plot this or use in other functions?

if x <= 0
y = -1 ;
elseif x > 0 && x <= 5
y = x^3 ;
elseif x > 5
y = x^2 ;
