------------------------------------
Hi Sandy,
I'm interested in this issue.
It seems that it is not difficult to implement the matrix operation to multiply
a RowMatrix and a Vector. What do you think about the operation to multiply a
Vector and a RowMatrix? I mean, `Vector.multiply(RowMatrix)`.
By the way, we are discussing about the matrix manipulation for large data set
in the issue. Just information.

> useful as well.
