AFAPI array scan (const array &in, const int dim=0, binaryOp op=AF_BINARY_ADD, bool inclusive_scan=true)
 C++ Interface generalized scan of an array.
 
AFAPI af_err af_scan (af_array *out, const af_array in, const int dim, af_binary_op op, bool inclusive_scan)
 C Interface generalized scan of an array.
 

Detailed Description

Inclusive or exclusive scan of an array.

Perform inclusive or exclusive scan using a given binary operation along a given dimension.

Binary operations can be add, mul, min, max as defined by af_binary_op.
