Specifically I need to take the dot product of a matrix and a vector and a matrix and a matrix. Was wondering if there is a theoretical reason or it just wasn't needed at the time. Looks like some of this got lifted from Spark (per the comments in the code, not trying to troll). I need dot products of matrices and vectors which isn't implemented. Thoughts? tg Trevor Grant Data Scientist https://github.com/rawkintrevo http://stackexchange.com/users/3002022/rawkintrevo http://trevorgrant.org *"Fortunate is he, who is able to know the causes of things." -Virgil* --089e01537ea2951bf6052c0da7da--
