Detailed Description

A slice of a sparse real interval matrix.

Represents a slice of a sparse real interval matrix. This helper class provides read and write access to such a slice using the standard operators. It should normally not be necessary for the user to explicitly work with this data type, which is why the constructors are private.

Member Function Documentation

interval& cxsc::simatrix_slice::element ( const int  i,
const int  j 
) [inline]

Returns a reference to the element (i,j) of the matrix.

Returns a reference to the (i,j)-th element. If the element is not explicitly stored, it is added as an explicit zero entry to the data structure. Using this function is faster than using A[i][j], since no temporary subvecto object must be created.

Definition at line 2782 of file simatrix.hpp.

Referenced by cxsc::simatrix_subv::operator[]().

const interval cxsc::simatrix_slice::operator() ( const int  i,
const int  j 
) const [inline]

Returns a copy of the element (i,j) of the matrix.

This operators can only be usd for read access. Note that accessing single elements of a sparse matrix is more expensive than for dense matrices and should in general be avoided.

Friends And Related Function Documentation

std::ostream& operator<< ( std::ostream &  os,
const simatrix_slice M 
) [friend]

Standard output operator for sparse matrix slice.

The output format is set by global flags, default is dense output. Use cout << SparseInOut; for sparse output or cout << MatrixMarketInOut; for output in matrix market format.
