Detailed Description

The C++ interface for setunion.

Creates a union of two sets

Function Documentation

array af::setunion	(	const array &	A,
		const array &	B
	)

Union of two vectors.

array a = array(seq(5));
array b = array(seq(5))-2*constant(1,5);
print(a);  //  0  1  2  3  4
print(b);  // -2 -1  0  1  2
array c = setunion(a,b);
print(c);  // -2 -1  0  1  2  3  4

Parameters

[in]	A
[in]	B

Returns

union of A and B

void af::setunion	(	array &	U,
		array &	IA,
		array &	IB,
		const array &	A,
		const array &	B
	)

Union of two vectors and their indices.

array a = array(seq(5));
array b = array(seq(5))-2*constant(1,5);
print(a);  //  0  1  2  3  4
print(b);  // -2 -1  0  1  2
array u, idxa, idxb;
setunion(u, idxa, idxb, a, b);
print(u);  // -2 -1  0  1  2  3  4
print(idxa);  // 0 1 2 3 4
print(idxb);  // 0 1

Parameters

[out]	U	values found in either A or B
[out]	IA	indices of values present in A
[out]	IB	indices of values present in B but not in A
[in]	A
[in]	B
