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]) | 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. |
| 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. |
