function

`scipy.fftpack._pseudo_diffs:shift`

source: build-install/usr/lib/python3.14/site-packages/scipy/fftpack/_pseudo_diffs.py:503

Signature

def shift(x, a, period = None, _cache = <_thread._local object at 0x0000>)

Summary

Shift periodic sequence x by a: y(u) = x(u+a).

Extended Summary

If x_j and y_j are Fourier coefficients of periodic functions x and y, respectively, then

y_j = exp(j*a*2*pi/period*sqrt(-1)) * x_f

Parameters

x : array_like: The array to take the pseudo-derivative from.
a : float: Defines the parameters of the sinh/sinh pseudo-differential
period : float, optional: The period of the sequences x and y. Default period is 2*pi.
