Class OpenMapRealMatrix

  • All Implemented Interfaces:
    java.io.Serializable, AnyMatrix, RealMatrix, SparseRealMatrix

    public class OpenMapRealMatrix
    extends AbstractRealMatrix
    implements SparseRealMatrix, java.io.Serializable
    Sparse matrix implementation based on an open addressed map.

    Caveat: This implementation assumes 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.
