Storing in VMatrix Cholmod.Sparse and Cholmod.Triplet — at Initial Version

Description

If we run this code:

VMatrix A = Triplet(SetOfSet(SetOfReal(1,1,9)), 8, 8);

VMatrix B = Mat2VMat(VMat2Mat(A));

Both VMatrix store the same number of cells (1/(8x8)=1.56%), however bytes stored are different:

A -> Stored bytes 72/552=13.04%

B -> Stored bytes 112/552=20.29%

I expected equal number of stored bytes. I suppose that store enging is quite different between Sparse and Triplet.
