Interface SparseRealMatrix

All Superinterfaces:
AnyMatrix, Blendable<RealMatrix>, 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.
