How to write diff (exp(x.*log(x))) on MATLAB command window?

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);

The syntax can work for my matlab version

>>  syms x
diff (exp(x.*log(x)))
 
ans =
 
exp(x*log(x))*(log(x) + 1)

I suspect that you have accidentally created a variable named one of diff or exp or log . Of those, it is most common for people to accidentally create diff

Thank you. I wil check again.

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