AFAPI array reorder (const array &in, const unsigned x, const unsigned y=1, const unsigned z=2, const unsigned w=3)
 
AFAPI af_err af_reorder (af_array *out, const af_array in, const unsigned x, const unsigned y, const unsigned z, const unsigned w)
 

Detailed Description

Reorder an array according to the specified dimensions.

Exchanges data of an array such that the requested change in dimension is satisfied. The linear ordering of data within the array is preserved.
