fftarray.Array.sel#

Array.sel(indexers: Mapping[str, float | slice] | None = None, missing_dims: Literal['raise', 'warn', 'ignore'] = 'raise', method: Literal['nearest', 'pad', 'ffill', 'backfill', 'bfill'] | None = None, **indexers_kwargs: float | slice) → Array[source]#

Select specific values along respective dimension names by label/coordinate. Inspired by xarray.DataArray.sel

Parameters:

  • indexers (Optional[Mapping[str, Union[float, slice]]], optional) – Mappping from Dimension name to the coordinate/label which can be a float or a slice, by default None

  • missing_dims (Literal['raise', 'warn', 'ignore']) – Behavior, if selected Dimensions are not part of the Array, by default ‘raise’

  • method (Literal['nearest', 'pad', 'ffill', 'backfill', 'bfill'] | None) –

    Method to use for inexact matches

    • None (default): only exact matches

    • pad / ffill: propagate last valid index value forward

    • backfill / bfill: propagate next valid index value backward

    • nearest: use nearest valid index value

  • indexers_kwargs (float | slice)

Returns:

Indexed Array.

Return type:

Array

Notes

In comparison to its xarray implementation, there is an add-on:

  • Implements missing_dims arg and accordingly raises errors
