We introduce kltool, a software package for extracting phase space information from complex spatiotemporal data using Karhunen-Loeve analysis. This tool simplifies processing and visualization for periodic, quasiperiodic, or chaotic systems.

Area of Science:

  • * Computational physics and data analysis.
  • * Nonlinear dynamics and complex systems.
  • * Scientific software development.

Background:

  • * Analyzing complex spatiotemporal data is crucial for understanding physical phenomena.
  • * Traditional methods may struggle with data from periodic, quasiperiodic, or chaotic systems.
  • * Extracting phase space information aids in characterizing system dynamics.

Purpose of the Study:

  • * To introduce kltool, a novel software package for phase space analysis.
  • * To enable easy processing and graphical display of complex spatiotemporal data.
  • * To demonstrate kltool's utility on diverse datasets.

Main Methods:

  • * Implementation of the Karhunen-Loeve analysis algorithm.
  • * Development of an interactive user interface for data processing and visualization.
