Set Functions

Array API specification for creating and operating on sets.

A conforming implementation of the array API standard must provide and support the following functions adhering to the following conventions.

• Positional parameters must be positional-only parameters. Positional-only parameters have no externally-usable name. When a function accepting positional-only parameters is called, positional arguments are mapped to these parameters based solely on their order.

• Optional parameters must be keyword-only arguments.

• Unless stated otherwise, functions must support the data types defined in Data Types.

Objects in API

unique_all(x, /)	Returns the unique elements of an input array x, the first occurring indices for each unique element in x, the indices from the set of unique elements that reconstruct x, and the corresponding counts for each unique element in x.
unique_counts(x, /)	Returns the unique elements of an input array x and the corresponding counts for each unique element in x.
unique_inverse(x, /)	Returns the unique elements of an input array x and the indices from the set of unique elements that reconstruct x.
unique_values(x, /)	Returns the unique elements of an input array x.
