This is used to specifiy a range of a vector. In general, a range is given by a start index, an extent, and a stride. The entire vector would be: start = 0, range = # elements, stride = 1
Stride specifies the stepsize of the vector. A stride of 2 means only every second element. This is particularly important in connection with matrices.
There are a number of special constructors for this class, of particular interest should be those using jokers, which provide a Matlab-like functionality.

Constructor with joker extent.
Depending on the sign of stride, this means "to the end", or "to the beginning".
Definition at line 627 of file matpackI.h.
Constructor with just a joker.
This means, take everything. You can still optionally give a stride, though. This constructor is just shorter notation for Range(0,joker)
Definition at line 637 of file matpackI.h.
Constructor which converts a range with joker to an explicit range.
max_size | The maximum allowed size of the vector. | |
r | The new range, with joker. |
Definition at line 648 of file matpackI.h.
Constructor of a new range relative to an old range.
The new range may contain -1 for the stride, which acts as a joker.
p | Previous range. | |
n | New range. |
