MATLAB: Set symbolic variables constant in plot

constantsurface plotsymbolic

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) )
