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.
