| C Interface to scan an array (generalized) over a given dimension, according to an array of keys. | |
Scan an array (generalized) over a given dimension, according to an array of keys.
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.
