URL: https://issues.apache.org/jira/browse/SOLR-11789
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Joel Bernstein
Now that we have *splines* and *derivatives* it makes sense to add
*integration*. The *integrate* Stream Evaluator will perform a Romberg
Integration (https://en.wikipedia.org/wiki/Romberg%27s_method) given a spline
and min and max values.
Implementation provided by Apache Commons Math
