Expression of a fixed-size or dynamic-size sub-vector.
VectorType | the type of the object in which we are taking a sub-vector |
Size | size of the sub-vector we are taking at compile time (optional) |
This class represents an expression of either a fixed-size or dynamic-size sub-vector. It is the return type of DenseBase::segment(Index,Index) and DenseBase::segment<int>(Index) and most of the time this is the only way it is used.
However, if you want to directly manipulate sub-vector expressions, for instance if you want to write a function returning such an expression, you will need to use this class.
Here is an example illustrating the dynamic case:
