Hi all. Today I came across a function f(X,Y) = cos(2*pi*X)(1+3Y) + ((2*pi*y)^2)/2.
I thought this was a 3d function but apparently it's not. How do i plot this 2D function in MATLAB.
Is there a special function for handling potential functions in MATLAB? thank you very much

f = @(X,Y) cos(2*pi.*X).*(1+3.*Y) + ((2*pi.*Y).^2)/2

Yes, you have independent 2 input variables and a resulting value which is usually shown in the 3rd dimension. But of course you also can show this in 2D by using:
fcontour(f)
This results in:
