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

2 views (last 30 days)
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
