List of evaluateStep() Examples

Examples of evaluateStep()

org.apache.commons.math.ode.events.CombinedEventsManager.evaluateStep()
Evaluate the impact of the proposed step on all managed event handlers. @param interpolator step interpolator for the proposed step @return true if at least one event handler triggers an eventbefore the end of the proposed step (this implies the step should be rejected) @exception DerivativeException if the interpolator fails tocompute the function somewhere within the step @exception IntegratorException if an event cannot be located
org.apache.commons.math.ode.events.EventState.evaluateStep()
Evaluate the impact of the proposed step on the event handler. @param interpolator step interpolator for the proposed step @return true if the event handler triggers an event beforethe end of the proposed step @exception DerivativeException if the interpolator fails tocompute the switching function somewhere within the step @exception EventException if the switching functioncannot be evaluated @exception ConvergenceException if an event cannot be located
org.apache.commons.math3.ode.events.EventState.evaluateStep()
Evaluate the impact of the proposed step on the event handler. @param interpolator step interpolator for the proposed step @return true if the event handler triggers an event beforethe end of the proposed step @exception MaxCountExceededException if the interpolator throws one becausethe number of functions evaluations is exceeded @exception NoBracketingException if the event cannot be bracketed
