function

scipy.signal._short_time_fft:_calc_dual_canonical_window

source: build-install/usr/lib/python3.14/site-packages/scipy/signal/_short_time_fft.py:38

Signature

def _calc_dual_canonical_window(win: np.ndarray, hop: int) → np.ndarray

Summary

Calculate canonical dual window for 1d window win and a time step of hop samples.

Extended Summary

A ValueError is raised if the inversion fails.

This is a separate function not a method, since it is also used in the class method ShortTimeFFT.from_dual().
