Absolute stability question - urgent! Hi, I wasn't too sure what section to put this in but I'm currently working on an exercise regarding absolute stability in the class Numerical Solutions of ODEs. Here is the graph i have produced on Matlab and I am suppose to comment on it. The graph shows the exact solution (black line) and the approximate solution of the given method with N = 70 when it is just stable. http://i16.tinypic.com/2e5ky0l.jpg" So far, I have made the comments that it can be observed that there is decreasing saw-tooth solution with smaller errors. For any values above N = 64, the errors will continue to decrease and the solution eventually converging. But I don't know if I am on the right track, can anyone help me out? Any additional comments I have left out would be helpful!
