Methods

__init__([distributions])

apply(waves[, in_place])

Apply tilt(s) to (an ensemble of) wave function(s).

copy()

Make a copy.

ensemble_blocks([chunks])

Split the ensemble into an array of smaller ensembles.

generate_blocks([chunks])

Generate chunks of the ensemble.

select_block(index, chunks)

Select a block from the ensemble.

Attributes

axes_metadata

List of AxisMetadata.

base_axes_metadata

List of AxisMetadata of the base axes.

base_shape

Shape of the base axes.

ensemble_axes_metadata

Axes metadata describing the ensemble axes added to the waves when applying the transform.

ensemble_shape

The shape of the ensemble axes added to the waves when applying the transform.

metadata

Metadata added to the waves when applying the transform.

shape

Shape of the ensemble.

apply(waves, in_place=False)[source]#

Apply tilt(s) to (an ensemble of) wave function(s).

Parameters:
  • waves (Waves) – The waves to transform.

  • in_place (bool, optional) – If True, the array representing the waves may be modified in-place.

Returns:

waves_with_tilt

Return type:

Waves

property axes_metadata: AxesMetadataList#

List of AxisMetadata.

property base_axes_metadata: list[AxisMetadata]#

List of AxisMetadata of the base axes.

property base_shape: tuple[int, ...]#

copy()#

Make a copy.

property ensemble_axes_metadata: list[AxisMetadata]#

Axes metadata describing the ensemble axes added to the waves when applying the transform.

ensemble_blocks(chunks=None)#

Split the ensemble into an array of smaller ensembles.

Parameters:

chunks (iterable of tuples) – Block sizes along each dimension.

Return type:

Array

property ensemble_shape#

The shape of the ensemble axes added to the waves when applying the transform.

generate_blocks(chunks=1)#

Generate chunks of the ensemble.

Parameters:

chunks (iterable of tuples) – Block sizes along each dimension.
