List of findRoot() Examples

Examples of findRoot()

bibliothek.gui.dock.common.CLocation.findRoot()
Gets the name of the station this location belongs to. This can be the id of any {@link CStation}. @return the name of the station or null if this locationdoes not have enough information to find the root
ca.nengo.math.RootFinder.findRoot()
@param function Function f(x) to find root of @param startLow Low-valued x from which to start search @param startHigh High-valued x from which to start. You typically give startLow and startHigh so thatyou expect the signs of the functions at these values to be different. @param tolerance Max acceptable |f(x)| for which to return x @return x for which |f(x)| <= tolerance
ca.nengo.math.impl.NewtonRootFinder.findRoot()
@see ca.nengo.math.RootFinder#findRoot(ca.nengo.math.Function,float,float,float)
io.fathom.cloud.persist.ZookeeperEntityTransaction.findRoot()
net.sf.doodleproject.numerics4j.root.BisectionRootFinder.findRoot()
Find a root of the target function that lies in the interval [ min, max]. @param min the lower bound of the search interval. @param max the upper bound of the search interval. @return a root that lies between min and max,inclusive. @throws NumericException if a root could not be found.
