Subject: [ublas] matrix reordering

I was looking for some ways to reorder my sparse matrices.
For the moment, the only way I see for this is to find the indices of
the original nonzeros and values to keep them in a triplet somehow then
try to create a mapping to the new ordering and assign according to this
mapping. I guess there are no direct ways implemented for this kind of
Or are there any better ideas?
A= diag[1 2 3] original order [1 2 3]
new order is [3 1 2] and B = diag([3 1 2])
