sets_union (MathScript RT Module Function)
Owning Class: sets
Requires: MathScript RT Module
Syntax
c = sets_union(a, b)
c = sets_union(a, b, 'rows')
[c, d, e] = sets_union(a, b)
[c, d, e] = sets_union(a, b, 'rows')
Legacy Name: union
Description
Returns the elements that are in at least one of the inputs.
Inputs
| Name | Description |
|---|---|
| a | Specifies a vector or matrix. |
| b | Specifies a vector or matrix. |
| 'rows' | Specifies that c returns the rows that are in a or b. You can specify this input when a and b are matrices with the same number of columns. |
Outputs
| Name | Description |
|---|---|
| c | Returns in ascending order the elements that are in a or b. If a contains repeated elements that also are in b, c contains as many of those repeated elements as are in a. c is a vector or matrix. |
| d | Returns the indexes in a of the elements in c. d is a vector of integers. |
| e | Returns the indexes in b of the elements in c. e is a vector of integers. |
Examples
A = [1, 2, 3, 4, 5, 6, 7, 8, 9]
B = [2, 3, 5, 7]
C = sets_union(A, B)
