> 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)
