----------------------------------------
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}
