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.
