How to draw a mesh !?

[Errant]

Hi,

I have the folliwng code in Matlab and I get the diagram below:

However, I need both x^2 + y^2 = 1 and z = x^2 be drawn in a mesh and the observer would tell them apart and would visualize the intersection as the picture above.

I hope you understand what I mean.

p = -3:0.1:3
x = sin(p);
y = cos(p);
z = x.^2;
plot3(x,y,z);
grid on;


Do you know how this code should be modified to give me what I need ?!

Have a look at contour, and the associated mesh commands, in the help. I haven't got to grips with them myself, yet.



Cheers
