Use arrayfun to call matlabFunction on each element of your symbolic array. In order for all the functions to have the same signature (the same input arguments) we need to precompute the list of variables used in expressions in A. The symvar function does that.
syms x y
A= [x x^2+y^2;x-y 2+y];
variablesInA = symvar(A)
c = arrayfun(@(z) matlabFunction(z, 'Vars', variablesInA), A, 'UniformOutput', false)
To check, let's call some of the functions.
c{1, 2}(3, 4) % 3.^2+4.^2 is 25
c{2, 2}(Inf, 5) % 5 + 2 is 7, x is not used
