Eigen::internal::BandMatrix Class Reference

---

Detailed Description

Represents a rectangular matrix with a banded storage.

Parameters:

_Scalar	Numeric type, i.e. float, double, int
Rows	Number of rows, or Dynamic
Cols	Number of columns, or Dynamic
Supers	Number of super diagonal
Subs	Number of sub diagonal
_Options	A combination of either RowMajor or ColMajor, and of SelfAdjoint The former controls storage order, and defaults to column-major. The latter controls whether the matrix represents a selfadjoint matrix in which case either Supers of Subs have to be null.
