(Plus AWESOME new index page)
Numerical Lyapunov
- Added method to estimate optimal delay time
estimate_delay
. - Added abstract
AbstractDataset
supertype. - Completely changed the way
Reconstruction
is done. - Added more methods, interaction and smart indexing related to the (new)
Reconstruction
object. See the new docstring ofreconstruct
for usage. - Added a new method that enables the calculation of the maximum Lyapunov
exponent from a numeric timeseries (like an experimental recording).
This method (callednumericallyapunov
) operates on a reconstruction, using
4 different algorithms. See the docstring ofnumericallyapunov
for
more info! - Added
double_pendulum
to famous systems.
Dataset + Speedup
v0.2.0: Major Improvements and new features
- Improved algorithm for deducing best boxsizes (using
min_pairwise_distance
) - All numerical data is now structured and expected to be in the
Dataset
Type,
which by itself defines a new interface (identical to matrix). - Major speed improvements in lyapunov function calculation.
- Major speed improvements in histogram computation.
- A new qr method for small matrices, faster than
Base.qr
(seeqr_sq
). - Reconstruction interface.
- New and better docs.
- Better integration of
SVectors
in the package all around. - Better default keywords for attractor dimension and lyapunov exponents.
- Equations of motion on all famous systems.
First release
This is a first release, and fully stable.
However future versions have much more contents!
Attractor Dimension Estimation
See the docs!
Histograms, entropies, linear regions (super-efficient)
Special histogram + Generilized dimensions HUGE update: Specialized histogram method that is 3 to 6 orders of magnitude more efficient than StatsBase histogram. Completed renyi. Made linear estimator that estimates linear scales and stuff. (automatic dimension estimation) What is left is to make direct methods (e.g. `boxcounting()` etc.)
Lyapunovs of Continuous systems
MASSIVE docs update I need to add tests and automated dimension estimation for renyi and then this chapter is also done.
Discrete Systems and Lyapunov exponents
v0.0.1 Create README.md
