This operator is only defined to allow one vector argument (num_targ_vecs == 1
) z[0]
. Using a reduction operator to set a sub-vector will be reasonably efficient for some types of vector subclasses (e.g. dense and sparse serial vectors and parallel vectors with client in every process) but very slow for others (e.g. out-of-core vectors and parallel vectors where operator object must be scattered to various processes). It would be better for vector subclasses to implement this operation directly but if they don't you can use this operator to set the required sub-vector.
This operator class works by allocating an internal sub-vector as the operator object state data.

int RTOp_TOp_set_sub_vector_construct | ( | const struct RTOp_SparseSubVector * | sub_vec, | |
struct RTOp_RTOp * | op | |||
) |
Constructor.
Note that a copy of sub_vec is not made. Therefore, the client must not disturb sub_vec
while this operator object is in use!

Reinitialize the range for the sub-vector to extract.
