How can I graph an equation with 'changing constant' values?

Hi,
I have a relatively straightforward question: How can I graph a surface with a changing 'constant' value depending on what the 'x' value is?
x = [-10:10];
y = [-10:10];
Constant = 5;
Equation = @(x,y) Constant + 5.*x + 5.*y;
%
where:
Constant = Constant + 10 for x < 3
Constant = Constant + 100 for x >= 3 > 6
Constant = Constant + 1000 for x >= 6
%
Thank you!

Equation = @(x,y) Constant + 10 + 90*(x>=3) + 900*(x>=6) + 5.*x + 5.*y;

Edit
x = [-10:0.1:10];
y = [-10:0.1:10];
Constant = 5+10*not(heaviside(x-3))+100*(heaviside(x-3)-heaviside(x-6))+1000*heaviside(x-6);
Equation = @(x,y,Constant) Constant + 5.*x + 5.*y;
z=Equation(x,y,Constant)
plot3(x,y,z)
%Or
x = [-10:0.1:10];
y = [-10:0.1:10];
Constant= 5+10*(x<3)+100*(x>=3 & x<6)+1000*(x>=6)
Equation = @(x,y,Constant) Constant + 5.*x + 5.*y;
z=Equation(x,y,Constant)
plot3(x,y,z)
