If syms is showing up as an undefined function, then either you are not licensed for the symbolic toolbox or else you do not have the symbolic toolbox installed.

MATLAB: Do I receive the error message “Symbolic Math Toolbox not available for this architecture” when using the Symbolic Math Toolbox

This error message may occur due to having specified the wrong operating system when installing the Symbolic Math Toolbox.

As a workaround, reinstall the Symbolic Math Toolbox, and be sure to specify the correct operating system with respect to the machine on which the toolbox is being installed.

Note that if you had installed MATLAB at the same time as installing the Symbolic Math Toolbox, you will need to reinstall MATLAB and all the associated toolboxes.

For more information about what platforms on which the Symbolic Math Toolbox is available, see the "Platforms and Requirements" page for the Symbolic Math Toolbox at the following URL:

MATLAB: How to expose a symbol from an equation? I have Symbolic Math Toolbox, if it is necessary

You have to set a few rules for the Symbolic Math Toolbox, but this is one possibility:

syms x y positive
assume(y > 2)
Eqn = y == x^2 + 2;
x = solve(Eqn)
x =
(y - 2)^(1/2)

EDIT — If you want to create an anonymous function from ‘x’, use the matlabFunction function.
