1) modify the line in operation.hpp marked with +/i in my diff
2) use axpy_prod(A,X,Y,true) for Y = prod(A,X)
and axpy_prod(A,X,Y,false) for Y += prod(A,X)

I should have atached it already :(
BTW. ublas' product of dense matrices is a lot slower than any optimized blas3
routine. However, you can use the atlasbindings to use blas instead of prod.
