Detailed Description

Reduction operator for counting the number of nonzero elements in a vector.

targ_obj <- size( { i | v[0](i) != 0.0, i=1...n } )

This operator is only defined to allow one vector argument (num_vecs == 1) v[0] but it can handle a dense or sparse vector. This operator will not count any explicit elments with v[0](i) == 0.0 in sparse or dense format. Therefore, this is the exact number of nonzero elements reguardless of storage format.
