Syntax
u[i] = x
y = v[i]

element_type
We use element_type to denote the type of elements in the vector. It must be one of the following types: bool, int, double, a_double.

i
This argument has prototype
     size_t i
It must be between zero and the size of the vector minus one.

u
The object u has prototype
     vec_element_type&   u

x
The argument x has prototype
     const element_type& x

v
The object v has the following prototype
     const vec_element_type& v

y
The result y has prototype
     element_type y

Octave
Note that Octave uses parenthesis () instead of brackets [] for element access.

Perl
Note that Perl does not support the element syntax above and instead uses set and get member functions.

Example
C++ , Octave , Perl , Python .
