It’s purpose is to index a vector.

For example: let’s say you have an array

 x = [1, 2, 3]

When the index mode is zero based then

x(0) gives 1

When it is one based then

x(1) gives 1

It is mainly used for indexing vector in loops.

Documentation is very brief , I suggest you to read it and go through the examples.
