Derivative a function according to another function

Hello
This is my code :
t= sym('t');
y(t)=sym('y(t)');
%Then i do some calculation but let's say that
T= 1/2*y(t)^2 %this is not my function but an exemple.
I try to differentiate T according to y. I try diff(T,y) and diff(T,y(t)), both don't work.
Do you have any clue how to do that ?
Thanks

Alexis, I believe functionalDerivative is what you are looking for:
t = sym('t');
y(t) = sym('y(t)');
T = 1/2*y(t)^2;
functionalDerivative(T,y)
ans(t) =
y(t)
