[jira] [Created] (SYSTEMML-2245) Missing support for external functions with variable number of outputs

Matthias Boehm created SYSTEMML-2245:
----------------------------------------

             Summary: Missing support for external functions with variable number of outputs
                 Key: SYSTEMML-2245
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-2245
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


Since the number of outputs of external functions are checked before execution (see {{ExternalFunctionProgramBlock.verifyFunctionInputsOutputs}}), it's currently impossible to implement user-defined external (i.e., java) functions with a variable number of outputs.
