rfourier_shape
calculates a 'Fourier radii variation shape' given
Fourier coefficients (see Details
) or can generate some 'rfourier'
shapes.
Arguments
- an
numeric
. The \(a_n\) Fourier coefficients on which to calculate a shape.- bn
numeric
. The \(b_n\) Fourier coefficients on which to calculate a shape.- nb.h
integer
. The number of harmonics to use.- nb.pts
integer
. The number of points to calculate.- alpha
numeric
. The power coefficient associated with the (usually decreasing) amplitude of the Fourier coefficients (see Details).- plot
logical
. Whether to plot or not the shape.
Details
rfourier_shape
can be used by specifying nb.h
and
alpha
. The coefficients are then sampled in an uniform distribution
\((-\pi ; \pi)\) and this amplitude is then divided by
\(harmonicrank^alpha\). If alpha
is lower than 1, consecutive
coefficients will thus increase. See rfourier for the mathematical
background.
