| Matrix Vector multiplication. | |
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 58 of file matpackI.cc.
References mstart.
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 68 of file matpackI.cc.
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. |

| ) | [friend] |
y = M*x. Note that the order is different from MTL, output comes first! Dimensions of y, M, and x must match. No memory reallocation takes place, only the data is copied. Using this function on overlapping MatrixViews belonging to the same Matrix will lead to unpredictable results. In particular, this means that A and B must not be the same matrix! The implementation here is different from the other multiplication routines. It does not use iterators but a more drastic approach to gain maximum performance.
