* Marker interface for {@link RealMatrix} implementations that require sparse backing storage

*
* Caveat: Implementation are allowed to assume that, for any {@code x},
* the equality {@code x * 0d == 0d} holds. But it is is not true for
* {@code NaN}. Moreover, zero entries will lose their sign.
* Some operations (that involve {@code NaN} and/or infinities) may
* thus give incorrect results.
