-----------------------------------
Summary: Call UDFs inline in the expressions without variables
Key: SYSTEMML-1785
URL: https://issues.apache.org/jira/browse/SYSTEMML-1785
Project: SystemML
Issue Type: Improvement
Reporter: Janardhan
Currently the usage of UDFs is restricted to simply being able to call the UDF
and assign the results to a variable. If the user wishes to use the UDF as
input to the builtin-op of any sort on the same line, an error is thrown. This
is confusing for users and leads to a messy code involving temporary variables.
example: {code:none} out = my_udf_func(x) + 4{code}
The UDFs should be treated like any other Op.
