Detailed Description

Weighted/unweighted sum operator at source in YAC.

This header defines the constructor for a source-side sum operator, expressed as a distributed matrix–vector product (MVP). Each target point is computed as the weighted sum of a number of source points. If the argument weights is NULL, the operator performs a simple unweighted sum instead.
