syms x t s X
>> Dx = diff(x,t);
D2x = diff(Dx,t);
Error using sym/subsindex (line 864)
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 909)
R_tilde = builtin('subsref',L_tilde,Idx);
