ArrayFire: setunique

Return the unique values in an array. More...

Return the unique values in an array.

The input must be a one-dimensional array. Batching is not currently supported.

An example, unsorted:

int h_set[6] = {3, 2, 3, 3, 2, 1};

A multi dimensional data container.

The function can be sped up if it is known that the inputs are sorted.

An example, sorted (ascending):

int h_set[6] = {1, 2, 2, 3, 3, 3};

const bool is_sorted = true;

unique = setUnique(set, is_sorted);

The inputs can be sorted in ascending or descending order.

An example, sorted (descending):

int h_set[6] = {3, 3, 3, 2, 2, 1};

const bool is_sorted = true;

unique = setUnique(set, is_sorted);
