This function is a variation of the MATLAB function called "ballode.m" supplied with MATLAB. If the event function is not a nested function, you need to pass the additional parameters to the event function. To pass the additional parameters, say "P1" and "P2", first define the event function 'MyEventFunction' with the additional inputs as follows:
Use event functions to detect when certain events occur during the solution of an ODE. Event functions take an expression that you specify, and detect an ...
When you switch from one set of ODEs to the other you need to specify the new ... post detailing aspects of stiffness and the methods available in Matlab.
Dec 07, 2012 · The events function receives both the current time and the current state vector. You can any or all of the elements of those to create each event. You are correct that more events functions and more complex events will slow down integration. The performance also depends on how often events are detected.
Use the 'Events' option of the odeset function to specify an event function. The event function must have the general form [value,isterminal,direction] = myEventsFcn (t,y) In the case of ode15i, the event function must also accept a third input argument for yp.
To pass the additional parameters, say "P1" and "P2", first define the event function 'MyEventFunction' with the additional inputs as follows: [ VALUE, ISTERMINAL, DIRECTION] = MyEventFunction (T, Y, P1, P2) The function associated with the EVENTS property in ODESET only takes 2 inputs (T,Y).
Use event functions to detect when certain events occur during the solution of an ODE. Event functions take an expression that you specify, and detect an event when that expression is equal to zero. They can also signal the ODE solver to halt integration when they detect an event. Writing an Event Function
See ODE Event Location for examples of ODE event functions that detect the bounces of a ball and orbits of celestial bodies. See Solve Oscillatory PDE with Event Logging for an example of a PDE event ... Run the command by entering it in the MATLAB Command Window.

08.08.2021 · When solving an ODE with MATLAB's ode45 solver, I'm trying to trigger an event to terminate the solution when a (general) boolean condition is satisfied. For example, in the code below, the condition is that x > 1.5 (because events trigger when value is zero, that is, when x <= 1.5 is false). Starting the solution from a point where the condition is satisfied at time zero, but …
06.12.2012 · In terms of implementation, here a simple example based on Matlab's ballode example, that simulates N ballistic particles in the vertical alone. There are N non-terminating events to catch the time and speed of each particle as it passes through y = 0.
