Benoit de Rancourt created MATH-805: ---------------------------------------
Summary: Percentile calculation is very slow when input data are constants Key: MATH-805 URL: https://issues.apache.org/jira/browse/MATH-805 Project: Commons Math Issue Type: Improvement Affects Versions: 3.0 Reporter: Benoit de Rancourt Priority: Minor I use the Percentile class to calculate quantile on a big array (10^6 entries). When I have to test the performance of my code, I notice that the calculation of quantile is at least 100x slower when my data are constants (10^6 of the same nomber). Maybe the Percentile calculation can be improved for this special case. -- This message is automatically generated by JIRA.
