Hi I have a function f dependent on 3 variables x,y,z. I want to plot f and also show a slice of f for a particular value of x,y,z in the same plot of f. For example let
x = -10:0.1:10;
y = -10:0.1:10;
z = -10:0.1:10;
f = x^2 + 3y^2 + exp(z);
How can i do this? Please help me out.

Hi
Thank You, Is there a direct function to plot f? What I want is a surface plot. But how do I use it for f?
Thanks
