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 ;
end

x = 0:0.01:10;

y = zeros(size(x)) ;

y(x <= 0) = -1 ;

y(x > 0 & x <= 5) = x(x > 0 & x <= 5).^3 ;

y(x > 5) = x(x > 5).^2 ;

plot(x,y)
