parents - ( ) left and right parenthesis
Left and right parenthesis are used to
* Specify evaluation order within expressions,
* Form right-hand-side functions argument list. Within multiple rhs arguments must be separated by comma.
* Select elements within vectors, matrices and lists. see help on extraction and insertion for more precisions
* [x1,x2,...]=(e1,e2,...) is equivalent to first performing %t_1 = e1, %t_2 = e2, ..., and then x1 = %t_1, x2 = %t_2, ..., where the variables %t_i, i = 1, 2, ... are invisible to the user.
