Index an array using another array.
Lets look at an example of how af::lookup function does indexing.
AFAPI af_err af_lookup | ( | af_array * | out, |
const af_array | in, | ||
const af_array | indices, | ||
const unsigned | dim | ||
) |
Lookup the values of input array based on index.
[out] | out | output array containing values at locations specified by index |
[in] | in | is input lookup array |
[in] | indices | is lookup indices |
[in] | dim | specifies the dimension for indexing |
