Katz / box-counting fractal dimension

Coarse box-counting on the amplitude-normalised signal across n_scales log-spaced box widths; returns the slope of log N(s) vs. log(1/s).

Usage

morie_dsp_katz_fd(x, n_scales = 10L)

Arguments

x

Numeric vector.

n_scales

Number of box sizes. Default 10.

Value

Scalar fractal dimension.
