template<typename FirstType, typename SizeType, typename IncrType>
class Eigen::ArithmeticSequence< FirstType, SizeType, IncrType >
This class represents an arithmetic progression \( a_0, a_1, a_2, ..., a_{n-1}\) defined by its first value \( a_0 \), its size (aka length) n, and the increment (aka stride) that is equal to \( a_{i+1}-a_{i}\) for any i.
It is internally used as the return type of the Eigen::seq and Eigen::seqN functions, and as the input arguments of DenseBase::operator()(const RowIndices&, const ColIndices&), and most of the time this is the only way it is used.
- Template Parameters
-
| FirstType | type of the first element, usually an Index, but internally it can be a symbolic expression |
| SizeType | type representing the size of the sequence, usually an Index or a compile time integral constant. Internally, it can also be a symbolic expression |
| IncrType | type of the increment, can be a runtime Index, or a compile time integral constant (default is compile-time 1) |
