I am trying to compute the derivative using the command diff:

syms x
diff (exp(x.*log(x)))

Error using sym/subsindex (line 853)

Invalid indexing or function definition. Indexing must follow MATLAB indexing. Function arguments must be symbolic

variables, and function body must be sym expression.

Error in sym/subsref (line 898)

R_tilde = builtin('subsref',L_tilde,Idx);

I guess so. It worked once I cleared my workspace. Thank you
