Hi Yuxi,
We are integrating the ml-matrix from the AMPlab repo into MLlib, tracked
by this JIRA: https://issues.apache.org/jira/browse/SPARK-3434
We already have matrix multiply, but are missing LU decomposition. Could
you please track that JIRA, once the initial design is in, we can sync on
how

Hey Yuxi,
We also have implemented a distributed matrix multiplication library in
PasaLab. The repo is host on here https://github.com/PasaLab/marlin . We
implemented three distributed matrix multiplication algorithms on Spark. As

There's been some work at the AMPLab on a distributed matrix library on top
of Spark; see here [1]. In particular, the repo contains a couple
factorization algorithms.

Hi,
Matrix computation is critical for algorithm efficiency like least square,
Kalman filter and so on.
For now, the mllib module offers limited linear algebra on matrix, especially
for distributed matrix.
We have been working on establishing distributed matrix computation APIs based
on data st
