Detailed Description

The range class.

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 & Destructor Documentation

Range() [1/5]

Range::Range ( Index  start, Index  extent, Index  stride = 1  )

inline

Definition at line 611 of file matpackI.h.

Range() [2/5]

Range::Range ( Index  start, Joker  joker, Index  stride = 1  )

inline

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.

Range() [3/5]

Range::Range ( Joker  joker, Index  stride = 1  )

inline

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.

Range() [4/5]

Range::Range ( Index  max_size, const Range &  r  )

inline

Constructor which converts a range with joker to an explicit range.

Parameters

max_size	The maximum allowed size of the vector.
r	The new range, with joker.

Definition at line 648 of file matpackI.h.

Range() [5/5]

Range::Range ( const Range &  p, const Range &  n  )

inline

Constructor of a new range relative to an old range.

The new range may contain -1 for the stride, which acts as a joker.

Parameters

p	Previous range.
n	New range.
