Set routines¶

Set operations for arrays based on sorting.

Making proper sets¶

unique(ar[, return_index, return_inverse, ...])

Find the unique elements of an array.

`in1d`(ar1, ar2[, assume_unique, invert])	Test whether each element of a 1-D array is also present in a second array.
`intersect1d`(ar1, ar2[, assume_unique, ...])	Find the intersection of two arrays.
`isin`(element, test_elements[, ...])	Calculates element in test_elements, broadcasting over element only.
`setdiff1d`(ar1, ar2[, assume_unique])	Find the set difference of two arrays.
`setxor1d`(ar1, ar2[, assume_unique])	Find the set exclusive-or of two arrays.
`union1d`(ar1, ar2)	Find the union of two arrays.
