scipp.scipy.signal.find_peaks

scipp.scipy.signal.find_peaks(da, *, height=None, threshold=None, rel_height=None, **kwargs)

A routine that locates “peaks” in a 1D signal.

This is a wrapper around :py:func:`scipy.signal.find_peaks. See there for a complete description of parameters.

Returns:

Variable – Indices of peaks in the signal that satisfy all given conditions.

Examples

>>> from scipp.scipy.signal import find_peaks
>>> x = sc.linspace('x', -3.14, 3.14, 101, unit='rad')
>>> y = sc.DataArray(sc.cos(5 * x), coords={'x': x})
>>> find_peaks(y)
<scipp.Variable> (x: 5)      int64        <no unit>  [10, 30, ..., 70, 90]
