Is it possible to evaluate symbolic functions from an array?

My idea was to simplify the working code

    syms x y
    f1(x,y) = x + y;
    f2(x,y) = x * y;

    A = [ [1,2]', [3,4]' ];

    H = A(:,1) * f1(x,y) + A(:,2) * f2(x,y);

by using:

    syms x y
    f1(x,y) = x + y;
    f2(x,y) = x * y;
    F = [f1, f2];

    A = [ [1,2]', [3,4]' ];

    H = 0;
    for i = 1 : length(A)
        H = H + A(:,i) * F(i)(x,y);
    end

Unfortunately, the term F(i)(x,y) gives rise to the error

    Cannot call or index into a temporary array

Given that the actual code uses much larger matrices and functions, writing out the summation of H becomes a pain in the neck. I would appreciate any hint which would allow me to automatize the process.
