Hello!

I want to make a surface plot using these variables:

x = (0:1:5); y = (-6:1:6);

The z formula, however, has an extra variable aw that directly corresponds to x.

That is, when x=0, aw=0.9; x=1, aw=0.8; x=2, aw=0.7, etc

Is there any way I could make this surface plot with this condition?

What is the formula for z in terms of x and y and aw?

z = 1/(C*(sqrt((aw-aminw))*(y-Tmin)-(x*f))^2; %C, aminw, Tmin and f are constants.

Looks like aw=.9-x/10. Just replace this in your equation.

My actual values are more random than the ones I stated here, (sorry about that) so I was wondering whether there is some function that addresses these variables together.

But you sure will have an equation which relates aw and x, don't you? Just use it inside your z equation. I don't know the relation, but if it's something nonsense as

aw=1+(2./x).^log(1-x.^2);

(no idea how that looks in reality), you change your equation

z = 1./(C*(sqrt((aw-aminw)).*(y-Tmin)-(x*f)).^2;

z = 1./(C*(sqrt((1+(2./x).^log(1-x.^2)-aminw)).*(y-Tmin)-(x*f)).^2;
