Partial Reduction (continued)
•All
associative operators can be used in partial form: +, *, max, min, &, |
•The
“singleton” dimension is “meaningful” in that the values are stored with like
indices
•E.g. [1..m,1] is stored with other
first column values
•Arrays
can have arbitrary dimension values if they have the right rank & elements
defined…
•E.g. Add row elements 2..n and store sum in 1st
position
•[1..m,1]
A := +<< [1..m, 2..n] A;
+
