Implicit differentiation

Can Matlab perform implicit differentiation?

Something like

>> diff(x^3 + y^2=4)

gives

>> (3x^2 x' + 2y y')

I could not find this info in the Doc, and the closest on the net is

http://en.wikibooks.org/wiki/MATLAB_Programming/Symbolic_Toolbox

but does not contain an example.

Thank you.
