Piecewise

CI codecov status

This repository contains three modules written in Julia:

  • Piecewise – Tools for defining piecewise functions made of user-defined elementary functions with parameters, called formulas. Properly configured formulas enable fast integral transforms of the piecewise function. The module defines seven formulas and a method for fitting a piecewise function with arbitrary formulas to a real function of a real variable.

  • PiecewiseHilbert – Add methods to the formulas defined in Piecewise, enabling fast Hilbert transform of the piecewise functions that use these formulas.

  • PiecewiseLorentz – Add methods to some of the formulas defined in Piecewise, enabling what we call a Lorentz transform of the piecewise functions.

Dependencies

HypergeometricFunctions  |  LsqFit  |  PolyLog

Installation

julia using Pkg; Pkg.add.(["Piecewise", "PiecewiseHilbert", "PiecewiseLorentz"]);

Contributing

Contributions and suggestions are welcome. If you're interested in contributing, please feel free to reach out via email. Bug reports can be submitted through the issue tracker, but email is preferred for quicker responses.

This policy may evolve if additional contributors become actively involved.

Expert input would be especially valuable in the following areas:

  • Evaluation performance: The evaluation of PiecewiseFunction objects appears to be slower than desirable. More efficient strategies to identify the relevant domain could yield significant improvements.

  • Parallel execution: The parallelism in piecewisefit could benefit from the scrutiny of those with a deeper understanding of Julia's parallel execution.
