Hi, Can you be more specific? Do you need sparse matrices to represent observation vectors because they are sparse? Or do you need sparse matrices to represent distance matrices because most vectors you are clustering are similar while a few are dissimilar?
The clustering code is written mostly in C and does not support sparse matrices. However, this should not matter because most of the clustering code does not look at the raw observation vectors themselves, just the distances passed as a distance matrix.
