Summary: Add support for colIndexMin/colIndexMax
Key: SYSTEMML-2226
URL: https://issues.apache.org/jira/browse/SYSTEMML-2226
Project: SystemML
Issue Type: Sub-task
Reporter: Matthias Boehm
SystemML already support {{rowIndexMin}} and {{rowIndexMax}} in the unary
aggregate framework, but in contrast to all other unary aggregates not its
column-wise operations. Hence, users are forced to specify and execute
unnecessary transpose operations.
This task aims to resolve this by adding the support for {{colIndexMin}} and
{{colIndexMax}}. In detail, this entails (1) adding new tests for these
aggregates, (2) extending the language layer by this new builtin function, (3)
extending the hop and lop compilation, and (4) adding the necessary runtime
support.
In separate PRs we further can introduce additional rewrites to remove
unnecessary operations in existing scripts.
