Owning Class: sets

Requires: MathScript RT Module


c = sets_unique(a)

c = sets_unique(a, 'rows')

[c, d, e] = sets_unique(a)

[c, d, e] = sets_unique(a, 'rows')

Legacy Name: unique


Removes repeated instances of input elements.



Name Description
a Specifies a vector or matrix.
'rows' Specifies that c returns the rows that are unique in a.


Name Description
c Returns in ascending order the unique elements of a. c is a vector or matrix.
d Returns the indexes in a of the elements in c. LabVIEW uses the index of the last occurrence of each unique element in a. If a is a matrix and you specify 'rows', d returns the row index in a of the rows in c. d is a vector of integers.
e Returns the indexes in c of the elements in a. If a is a matrix, e returns the row index in c of the rows in a. e is a vector of integers.


The following table lists the support characteristics of this function.

Supported in the LabVIEW Run-Time Engine Yes

A = [1, 2, 3, 4, 5, 6, 7, 8, 9, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
C = sets_unique(A)

A = [1, 2, 3; 4, 5, 6; 1, 2, 3]
[C, D, E] = sets_unique(A, 'rows')
