components of vector valued functions

Given
F=@(x,y) [x+y,x-y.^2]
how do I refer to the second component of that function;
the command
syms x,y; F(x,y)(2)
gives an error, though I would expect to get x-y^2. My goal is to define a new function which only contains one particular component of a vector field like
f2=@(x,y) F(x,y)(2)
Probably simple but I did not find the correct syntax.

VSelect = @(V,IDX) V(IDX);
F = @(x,y) [x+y,x-y.^2]
f2 = @(x,y) VSelect(F(x,y),2);
There is no good direct way to do it. There is a way to do it all in one function call, but it is somewhat ugly and not easy to read.
