Example of Referring elements:
the vector can also be extended. For illustration, the following generates a vector which has three elements. And then referring to the fourth element in an assignment statement, the vector is then extended to have four elements.
>> rv = [3 55 11]
rv =
3 55 11
>> rv(4) = 2
rv =
3 55 11 2
If there is a gap between the ends of the vector and the specified element, 0's are filled in. For illustration, the following extend the variable generated former again:
>> rv(6) = 13
rv =
3 55 11 2 0 13
