Reductions

  • a scalar is a single value
  • a vector is an ordered set of values
  • a reduction produces a scalar from a vector: intVector A(10); int x; A = 4; x = sum(A); // x gets the sum of all elements of A x = min_value(A); // x gets the minimum of all elements of A x = max_value(A); // x gets the maximum of all elements of A . . .
