ODE45 Iterations details
显示 更早的评论
Dear Matlabers,
I worked previously on Optimization Algorithms (Built-in ones). And there were built-in functions to know what is going on for every iteration, and what is the error.
Similarly, I want to know what are the output for every ode45 iteration. How can I?
i0 = [0 0 0 0];
[t, sol] = ode45(fun,[0 20], i0);
Thanks in advance

Display time and sol values either in a function "OutputFcn" or - quick and dirty - directly in "fun" during the solution process.
Concerning "OutputFcn", read the documentation for options of ode45.

The "Summary of ODE Examples and Files" section of this documentation page lists various examples included in MATLAB and the options that those examples use. The ballode and orbitode examples indicate they use the OutputFcn option. I would start by reading through those examples and trying to understand them.
