Device pointer interface: Shift is device pointer
Shift the contents of an array along specified dimensions and wrap. Parameters [out] d_out Shifted array [in] ndims Number of dimensions in array dims [in] dims Array of dimensions [in] nshifts Number of shifts in array shifts [in] d_shifts Array(on device) indicating extent of shift along each dimension, e.g. [1 0 -2] shifts forward once in first dimension, none in second dimension, and back twice in third dimension. [in] d_in Original array. [in] batch Number of tiles of input. [in] batch_shift Number of tiles of shift.

Detailed Description

The C interface for shiftd.

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]
