I'd like to choose the appropriate ublas matrix type for a matrix that has very
few non-zero entries in each row, but every row has atleast a few non-zeros. (In
fact, every row has exactly three of them).
Let's call this matrix J. I'd like to perform matrix multiplies M * trans(J) and
vector multiplies J * x efficiently. Which of the ublas sparse types
(compressed_matrix, gvov, ...) have those matrix-matrix multiplies specialized?
