>> F(A,B,C) = 3 + 9^2 + pi

Undefined function or variable 'A'.

>> syms A  B C

Error using sym/subsindex (line 836)

Invalid indexing or function definition. Indexing must follow MATLAB indexing. Function

arguments must be symbolic variables, and function body must be sym expression.

>> syms A  B C F

Error using  ^

One argument must be a square matrix and the other must be a scalar. Use POWER (.^) for

elementwise power.
