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.
