hyperfine.utilities.sampling_index

hyperfine.utilities.sampling_index(array: Sequence[T], n_elements: int, begin_offset: int = 0, end_offset: int = 0) → Sequence[T][source]

Sample evenly spaced indices from an array.

Inspired by: https://stackoverflow.com/a/50685454

Parameters:

array – The array to sample indices from.
n_elements – Number of indices to select.
begin_offset – Offset from array’s beginning index when sampling.
end_offset – Offset from array’s ending index when sampling.

Returns:

An array of the sampled indices.

Example

import numpy as np
from hyperfine.utilities import sampling_index

a = np.linspace(0.0, 30.0, 100)

n_elem = 5,
beg_off = 0
end_off = 0
idx = sampling_index(a, n_elem, beg_off, end_off)
