Interface SparseRealMatrix

All Superinterfaces:

AnyMatrix, RealMatrix

All Known Implementing Classes:

OpenMapRealMatrix

public interface SparseRealMatrix
extends RealMatrix

Marker interface for RealMatrix implementations that require sparse backing storage

Caveat: Implementation are allowed to assume that, for any x, the equality x * 0d == 0d holds. But it is is not true for NaN. Moreover, zero entries will lose their sign. Some operations (that involve NaN and/or infinities) may thus give incorrect results.

Since:
