Detailed Description

The C++ interface for shift.

array a(seq(5)); //a=[0 1 2 3 4]
a = shift(a,2);  //a=[3 4 0 1 2]
array a(seq(5)); //a=[0 1 2 3 4]
array b = constant(1,1,af::s32);
a = shift(a,b);  //a=[4 0 1 2 3]

Function Documentation

array af::shift	(	const array &	in,
		int	dim0 = 0,
		int	dim1 = 0,
		int	dim2 = 0,
		int	dim3 = 0
	)

Shift the values of an array around dimension (wrap around).

array a(seq(5)); //a=[0 1 2 3 4]
a = shift(a,2);  //a=[3 4 0 1 2]

Parameters

[in]	in
[in]	dim0	Shift along first dimension
[in]	dim1	Shift along second dimension
[in]	dim2	Shift along third dimension
[in]	dim3	Shift along fourth dimension

Returns

shifted version of array

array af::shift	(	const array &	in,
		const array &	shift
	)

Shift the values of an array around dimension (wrap around).

array a(seq(5)); //a=[0 1 2 3 4]
array b = constant(1,1,af::s32);
a = shift(a,b);  //a=[4 0 1 2 3]

Parameters

[in]	in
[in]	shift	integer array (s32 preferred) indicating shifts for each dimension

Returns

shifted version of array
