List of determineAlphaMinMax() Examples

Examples of determineAlphaMinMax()

de.lmu.ifi.dbs.elki.data.ParameterizationFunction.determineAlphaMinMax()
Determines the alpha values where this function has a minumum and maximum value in the given interval. @param interval the hyper bounding box defining the interval @return he alpha values where this function has a minumum and maximum valuein the given interval

Examples of de.lmu.ifi.dbs.elki.data.ParameterizationFunction.determineAlphaMinMax()

      Double f_min = minima.get(id);
