Set symbolic variables constant in plot

Hi all,

I have the symbolic function

f = 2*a^2*b^2 - 2*a^2*b + 5*a^2 - 2*a*b^3 - 2*a*b^2*c

and want to see a surface plot of this for c = 0.

I imagine I want to use the ezsurfc() function but how do I specify that I want to hold the symbolic variable 'c' constant and equal to 0?

Many thanks, Rob

ezsurfc( subs(f, c, 0) )
