Tridiagonal function matlab
WebI'm attempting to pass three parameters to my MATLAB event function - as opposed to just the normal two (t,y) - in order to solve an orbital dynamics problem, but the method I currently have implemented does not work. I believe the following code should work, but when run, the event never records an iteration step, ...
