Hey Phil,

Depending on my previous ublas experience, the only way, I see, would be 
to initilize a csc matrix from the triplets of a csr matrix, then the 
internal structure is in the format that we want. And for my application 
I need the triplets of the column oriented matrix and I have some codes 
for this already to extract this data it is a bit interfacing overhead 
though.

I guess there is no direct way for this, let me know if you have better 
workarounds...

Best,
Umut
