Software

mf_bs_tool

Matlab toolbox to perform p-leader based multifractal analysis.

Main features:

rangesel: Scaling range selection

Performs the bootstrap-based scaling range selection algorithm for wavelet leader multifractal analysis, as described in this paper. Works with the wavelet-leader multifractal analysis toolbox WLBMF available here.

This software is outdated. A new version is bundled in the p-leader based multifractal analysis toolbox presented before.
