Abstract
We announce the availability of a software package, called kltool, that can extract phase space information from complex spatiotemporal data via the Karhunen–Loève analysis. Data generated by the periodic, quasiperiodic or chaotic evolution of a small number of spatially coherent structures can be processed. A key feature of kltool is that it allows the user to interact easily with the data processing and its graphical display. We illustrate the use of kltool on numerical data from the Kuramoto–Sivashinsky equation and laboratory data from a flame experiment.Keywords
