Here's the code. I want to show only X values between 0 and 1. Y values between 0.001 and 1000, and adjust the Z automatically.

YS = @(X,Y)  (0.38*X^2-0.31*X-0.02)*log(Y)+2.7287*sin(1.1732*X+1.1613);
%the coefficients are not constant numbers, this is just an example.
fsurf(Z);
xlim ([0 1]);
ylim ([0.001 1000]);

When I first plot the surface, this is how it looks like:

After I double click on the plot, it adjusts the Z automatically to this:

How do you get the second/correct view without interacting with the plot?

Use zlim as well.

zlim([-3 3])

I would rather prefer:

x = linspace(0,1) ;

y = linspace(0,1000) ;

[X,Y] = meshgrid(x,y) ;

Z = (0.38*X.^2-0.31*X-0.02).*log(Y)+2.7287*sin(1.1732*X+1.1613);

%the coefficients are not constant numbers, this is just an example.

surf(X,Y,Z);
