RTOpPack: Extra C/C++ Code for Vector Reduction/Transformation Operators Version of the Day
Reduction operator for the dot product of two vectors.
targ_obj <- sum( v(i) * v(i), i=1...n )
This operator is defined to allow exactly two vector arguments (
num_vecs == 2)
v, and it can handle all combinations of sparse and dense vectors.
