See expval_base for some general notes on this and related classes.
This is a similar to expval_scalar, except that it allows updating and statistics for a set of scalars en masse. The data is stored internally in ublas vector and matrix object, but the public member functions operate with template types which are compatible with any vector class which provides double &operator[]
. It is assumed that each call to add() contains a new measurement for all of the vector indices.
