Specifies an advanced indexing operation.

Dimension expressions permit indexing using dimension labels, and also support additional operations that cannot be performed with plain NumPy indexing.

Operations¶

__getitem__(indices: Any) -> DimExpression[source]

Applies a NumPy-style indexing operation with default index array semantics.

property diagonal: DimExpression

Extracts the diagonal of the selected dimensions.

label(labels: str | collections.abc.Sequence[str]) -> DimExpression

Sets (or changes) the labels of the selected dimensions.

translate_to(origins) -> DimExpression

Translates the domains of the selected input dimensions to the specified origins without affecting the output range.

vindex(indices: Any) -> DimExpression

Applies a NumPy-style indexing operation with vectorized indexing semantics.
