Institution: INAOE

INSTRUCTIONS:

1. Run the Main_StepSize.m

2. Introduce the next inputs correctly.

Inputs:

system = Name of system to evaluate(@NameOfSystem)

yi = Initial Conditions

h = Step-size

evals = Number of evaluations over time

tini = Initial Time of Integration

tfin = Final Time of Integration

3. Define in the same folder path, the chaotic system in a Matlab

script as a function f(t,y) type called “osc_caseh.m”, for example.

4. Press the "start" button and wait the results. The output will be:

The Recommended step sizes for the solution of the chaotic

"system" with different numerical integration methods.
