Component/s: MLlib

Labels:None
Description
MLlib's local linear algebra package doesn't have any support for any type of matrix operations. With 1.5, we wish to add support to a complete package of optimized linear algebra operations for Scala/Java users.
The main goal is to support lazy operations so that elementwise can be implemented in a single forloop, and complex operations can be interfaced through BLAS.
