Package org.hipparchus.linear

Class SparseRealVector

  • Direct Known Subclasses:
    OpenMapRealVector
    public abstract class SparseRealVector
extends RealVector
    Marker class for RealVectors 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, like multiplications, divisions or functions mapping.

        public SparseRealVector()
        Empty constructor.

        This constructor is not strictly necessary, but it prevents spurious javadoc warnings with JDK 18 and later.
