Thank, I will bother you with one more question if you do not mind ;-)

I had a confusion at some point in the attached program, why is the 
output of the attached program is

[4,4]((1,0,0,5.5),(0,0,2.3,2),(0,0,4,0),(0,0,0,5.5))
Size of nonzeros : 6
0, 2, 4, 5, 6,              \\ if this is CSR format why is not 
(row_ptr(n+1) == nnz+1), 6 in this case
0, 3, 2, 3, 2, 3, 0, 0,  \\ what are the extra 0 zeros
1, 5.5, 2.3, 2, 4, 5.5, 0, 0, \\ also here.

Best,
Umut
