defining an unknown function

Hi all, I would like to start by defining H = {{\partial_{x,x} L,\partial_{x,y} L}, {\partial_{y,x} L, \partial_{y,y} L}}; where at this stage, the only think i know is that L is of the form L(x,y). This is a Hessian, and I would like to symbolically compute the evals and evecs. I wanted to know how I should tell mathematica to consider L as L(x,y) ?
Thanks, Sid.
