I'm trying to draw a parabola in 3D. However, I want to limit its extents.
I am able to limit the X and Y extents pretty easily, through the function.
ie: which limits the x to 0 to 2, and the y from -5 to 1.
X=linspace(0,2,20);
Y=linspace(-5,1,20);
However, the Z, I want to limit this aswell. So I used:
zlim([0 4])
It worked, but now my entire 3D domain is cropped! and I need to show other elements.
Any idea on how this can be achieved? I suspect my function is a bit primitive.
Sorry, I'm matlab illiterate but just starting out. I don't know enough to ask this question properly. THANK YOU for any Help!
total code:
%Curve, parabola in 3d, with limits
X=linspace(0,2,20);
Y=linspace(-5,1,20);
[X,Y]=meshgrid(X,Y);
Z=((Y.^2));
surf(X,Y,Z);
%Limit the Z axis
zlim([0 4])
%basic graphics
x1=[-3 3 3 -3];
y1=[0 0 0 0];
z1=[0 0 6 6];
patch(x1,y1,z1, [0.71 0.72 .73]);

One possibility.
X=linspace(0,2,20);
Y=linspace(-5,1,20);
[X,Y]=meshgrid(X,Y);
Z=((Y.^2));
Z(Z>=4)=nan;
surf(X,Y,Z);
%basic graphics
x1=[-3 3 3 -3];
y1=[0 0 0 0];
z1=[0 0 6 6];
patch(x1,y1,z1, [0.71 0.72 .73]);
view(-75,25);
