Joel Bernstein updated SOLR-13776: ---------------------------------- Description: The *derivative* Stream Evaluator operates over functions (spline, lerp, akima, loess, polyfit, oscillate etc...), but does not work with the function created by the derivative function. This means a spline needs to be wrapped around the derivative to take a second derivative. This ticket will allow the derivative function to applied directly to output of the derivative function. (was: Currently the *derivative* Stream Evaluator operates over functions (spline, lerp, akima, loess, polyfit, oscillate etc...). It would be useful if the *derivative* function could operate directly over a vector.) > Allow derivatives to be computed from derivatives > ------------------------------------------------- > > Key: SOLR-13776 > URL: https://issues.apache.org/jira/browse/SOLR-13776 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level.
