Collection of the Lyapunov exponents over time

[rseydam]

Is it possible to collect the computed Lyapunovspectra over time to check on the convergence of the exponents?

Closing in favor of the discussion of #317 , as the answer here is similar:

This option is not available out of the box. It will likely not be available out of the box in the near future either. That is because adding auxilary options for every possibility some user will find useful would obfuscate the code and reduce code clarity, making more than 50% of the lines of code auxilary options rather than computing Lyapunov exponents. To add this option you can trivially create a custom function by

1. You copy paste this function: https://github.com/JuliaDynamics/ChaosTools.jl/blob/main/src/chaosdetection/lyapunovs/lyapunovspectrum.jl#L67-L99 and rename it to mylyapunovspectrum,
2. You add the exponents_history = [zeros(k)] at the start of the function.
3. In the core step loop, right after https://github.com/JuliaDynamics/ChaosTools.jl/blob/main/src/chaosdetection/lyapunovs/lyapunovspectrum.jl#L89 you add the line push!(exponents_history, λ ./ (current_time(tands) - t0)).
4. You change the return statement to return λ, exponent_history.
