Set routines¶
Making proper sets¶
unique (ar[, return_index, return_inverse, …]) |
Find the unique elements of an array. |
Boolean operations¶
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. |
