AFAPI array | scanByKey (const array &key, const array &in, const int dim=0, binaryOp op=AF_BINARY_ADD, bool inclusive_scan=true) |
C++ Interface generalized scan by key of an array. | |
AFAPI af_err | af_scan_by_key (af_array *out, const af_array key, const af_array in, const int dim, af_binary_op op, bool inclusive_scan) |
C Interface generalized scan by key of an array. | |
Inclusive or exclusive scan of an array by key.
Perform inclusive or exclusive scan using a given binary operation along a given dimension using a key.
Binary operations can be add, mul, min, max as defined by af_binary_op.
