How do I plot a 3d shape from a function?

I have to plot the following function:

where [c1,c2,c3,c4] = [2.13,2.22,2.62,0.177]

Is there a way of doing this?

Thank you

There is a good example here.

x = -2:0.25:2;
y = x;

if you want to visualize this , then

surf(x,y,x.*exp(-x.^2 -(y').^2))

The point here is y', which enables an implicit expansion. (See here)

You can also perform the same thing by using meshgrid function - this might be easier for you to understand this..
