             Summary: Extend `util::pad_image` with a `pad_value` parameter
                 Key: SYSTEMML-1432
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1432
             Project: SystemML
          Issue Type: Sub-task
            Reporter: Mike Dusenberry
            Assignee: Mike Dusenberry
            Priority: Minor


Currently, our {{util::pad_image}} function performs zero-padding, which is correct for operations such as convolution.  In some cases, such as max pooling, it is necessary to pad with a different value such as negative infinity.  Therefore, we should extend our {{util::pad_image}} function to accept a {{pad_value}} parameter with a noted typical value of 0.
