-----------------------------------------
Thank you [~mboehm7]. I'll take a look at that too. I will let you know if I
need any guidance.
> JMLC/MLContext support for scalar output variables
> --------------------------------------------------
>
> Key: SYSTEMML-649
> URL: https://issues.apache.org/jira/browse/SYSTEMML-649
> Project: SystemML
> Issue Type: Task
> Components: APIs
> Reporter: Matthias Boehm
> Assignee: Deron Eriksson
>
> Right now neither JMLC nor MLContext supports scalar output variables. This
> task aims to extend both APIs with the required primitives.
> The workaround is to cast any output scalar on script-level with as.matrix to
> a 1-1 matrix and handle it in the calling application. However, especially
> with MLContext this puts an unnecessary burden on the user as he needs to
> deal with RDDs for a simple scalar too.
