Detailed Description

Represents a row or column vector of a sparse matrix.

This is a helper class created by the [] operator to represent a row or column of a sparse matrix. This helper class provides read and write access to the subvector using the standard operators. It is normally not necessary for the user to use this class explicitly, which is why the constructors are private.

Member Function Documentation

real& cxsc::srmatrix_subv::operator[]

(

const int

i

)

[inline]

Returns a reference to the i-th element of the subvector.

A refernce to the i-th element is returned. If this element is not explicitly stored, it is added as an explicit zero entry to the data structure.

Definition at line 2179 of file srmatrix.hpp.

const real cxsc::srmatrix_subv::operator[]

(

const int

i

)

const [inline]

Returns a copy of the i-th element of the subvector.

A copy to the i-th element is returned. If this element is not explicitly stored, 0 is returned
