unique

Unique-related operations.

The skrough.unique module delivers helper functions for unique-related computations. Currently all operations are simple wrappers around numpy.unique() but they are here to provide interfaces that the rest of the code uses.

Functions

get_rows_nunique(x)	Compute the number of unique rows.
get_uniques(values)	Get unique values.
get_uniques_and_compacted(values)	Get unique values and compacted version of an input array.
get_uniques_and_positions(values)	Get unique elements of an array and indices of first occurrences of these values.
get_uniques_positions(values)	Get positions of first occurrences of unique values.
