[jira] Resolved: (MATH-334) RealVector (or ArrayRealVector): support min and max element

["Luc Maisonobe (JIRA)" <ji...@apache.org>]

Luc Maisonobe resolved MATH-334.
--------------------------------

    Resolution: Fixed

Fixed in subversion repository as of r904231.
Four methods have been added: getMinIndex, getMinValue, getMaxIndex and getMaxValue. Specila cases handled are zero length vectors and vectors with only NaNs. When both NaNs and regular values are present, min and max are computed on regular values only.

For compatibility reasons, these methods have been put in the topmost abstract class but not in the interface yet. It could be pushed to the interface when next major version will be released.
