Detailed Description

template<typename _Scalar, int _Options>
class Eigen::SkylineMatrix< _Scalar, _Options >

The main skyline matrix class.

This class implements a skyline matrix using the very uncommon storage scheme.

Parameters

_Scalar	the scalar type, i.e. the type of the coefficients
_Options	Union of bit flags controlling the storage scheme. Currently the only possibility is RowMajor. The default is 0 which means column-major.
