------------------------------------
Resolution: Fixed
> Matrix operations (phase 2)
> ---------------------------
>
> Key: MADLIB-906
> URL: https://issues.apache.org/jira/browse/MADLIB-906
> Project: Apache MADlib
> Issue Type: New Feature
> Reporter: Frank McQuillan
> Assignee: Rahul Iyer
> Fix For: v1.9
>
> Attachments: MADlib_ Matrix Operations.pdf
>
>
> Background
>
> Phase 1 of matrix operations was released as part of 1.8
> https://github.com/madlib/madlib/blob/v1.8/ReleaseNotes.txt
> http://doc.madlib.net/latest/group__grp__matrix.html
> This jira for phase 2 is to add additional matrix operations.
> Story
> Decomposition operations:
> -- Matrix inverse
> matrix_inverse( matrix_in, in_args, matrix_out, out_args)
>
> -- Matrix generic inverse
> matrix_pinv( matrix_in, in_args, matrix_b, b_args, matrix_out, out_args)
>
> -- Matrix eigen extraction
> matrix_eigen( matrix_in, in_args, matrix_out)
>
> -- Matrix cholesky decomposition
> matrix_cholesky( matrix_in, in_args, matrix_out_prefix, out_args)
>
> -- Matrix QR decomposition
> matrix_qr( matrix_in, in_args, matrix_out_prefix, out_args)
>
> -- Matrix LU decomposition
> matrix_lu( matrix_in, in_args, matrix_out_prefix, out_args)
>
> -- Matrix nuclear norm computing
> matrix_nuclear_norm( matrix_in, in_args)
>
> -- Matrix rank computing
> matrix_rank( matrix_in, in_args)
