parents — ( ) left and right parenthesis
(expression) [...]=func(e1,e2,...) [x1,x2,...]=(e1,e2,...) x(i,j) v(i) [...]=l(i)
| x | : matrix of any possible type |
| v | : row or column vector of any possible type |
| l | : list variable |
| func | : any function name |
| e1,e2,... | : any possible type expression |
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.
