Figure 2.14 Broadcast and reduction.
Broadcasts Broadcasts are created when there exists a vector v in Null(Q),
which is not in Null(P ). Refer to Figure 2.14a. If v is the vector separating
two points in D and v is in the null space of Q, then the two points in D
will map to the same point in D(Y ). If v is not in the null space of P , then
these two points will map to two distinct points in D(X). This means that
two or more values in X are dependent on a single value in Y and this is a
broadcast.
Reductions Refer to Figure 2.14b. If v is in the null space of ...
