%% Create Symbolic Functions
% Create symbolic functions with one and two arguments.

syms s(t) f(x,y)

% Both s and f are abstract symbolic functions. They do not have symbolic expressions assigned to them, so the bodies of these functions are s(t) and f(x,y), respectively.
% Specify the following formula for f.

f(x,y) = x + 2*y

% Compute the function value at the point x = 1 and y = 2.

f(1,2)
