             Summary: Add Default Parameter Values to UDFs
                 Key: SYSTEMML-589
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-589
             Project: SystemML
          Issue Type: Sub-task
            Reporter: Mike Dusenberry


This task aims to add default parameter values to UDFs for scalar and boolean types.  There may already be runtime support, but the grammar does not seem to allow it.

Example that currently works:
{code}
script = """
f = function(double x, int a) return (double ans) {
  ans = a * x
}

ans = f(3, 1)
print(ans)
"""
ml.reset()
ml.executeScript(script)
{code}

Example that would be nice:
{code}
script = """
f = function(double x, int a=1) return (double ans) {
  ans = a * x
}

ans = f(3)
print(ans)
"""
ml.reset()
ml.executeScript(script)
{code}
