---------------------------------------
I want to add this feature in any of the coming versions. Kindly let me know
how this can be done.
> Matrix Inversion on BlockMatrix
> -------------------------------
>
> Key: SPARK-23266
> URL: https://issues.apache.org/jira/browse/SPARK-23266
> Project: Spark
> Issue Type: New Feature
> Components: MLlib
> Affects Versions: 2.2.1
> Reporter: Chandan Misra
> Priority: Minor
>
> Matrix inversion is the basic building block for many other algorithms like
> regression, classification, geostatistical analysis using ordinary kriging
> etc. A simple Spark BlockMatrix based efficient distributed
> divide-and-conquer algorithm can be implemented using only *6*
> multiplications in each recursion level of the algorithm. The reference paper
> can be found in
> [https://arxiv.org/abs/1801.04723]
