What error message you get? Share the screenshot of the entire red text you get when running this command.

"How can I verify that I have symbolic calculation enabled?"

Enter ver in the command window and see if you have the Symbolic Math Toolbox installed or not.

You need to install the Symbolic Toolbox

If you are lucky, then possibly you already have a license for it. Use the Add-On Explorer and search for Symbolic Toolbox. If you already have a license for it then there will be a button to install the toolbox.

Is this what you are trying to achieve (È questo ciò che stai cercando di ottenere?):

% Initialize symbolics
syms H(x) F(x,y) G(x, y, z)
% Initialize symbolic functions
H(x) = sin(x)

H(x) = 

F(x, y) = x^2+y^2+2*x*y

F(x, y) = 

G(x, y, z) = sqrt(x^2+y^2+z^2-25)

G(x, y, z) = 

% Calculations:
H(pi)

0

F(1, 2)

ans =

G(1, 2, 3)
