Detailed Description

Like MemoryVMatrix this class holds the data in memory. But it is designed to keep a compact representation of sparse matrices, keeping for each row only the position and values of the non-zero elements. The values are stored as floats regardless whether we ar in USEFLOAT or USEDOUBLE mode.
