An '''''array-reducing function''''' operates over an index of an array and returns a result without that index. For example, if x is indexed by i, j, and k, Sum(x, k) sums x over k, so its result is indexed by i and j, but not k. Most array-reducing functions can operate over multiple indexes. For example, Sum(x, i, j) sums x over i and j, returning a result indexed only by k. | An '''''array-reducing function''''' operates over an index of an array and returns a result without that index.

An array-reducing function operates over an index of an array and returns a result without that index. For example, if x is indexed by i, j, and k, Sum(x, k) sums x over k, so its result is indexed by i and j, but not k. Most array-reducing functions can operate over multiple indexes. For example, Sum(x, i, j) sums x over i and j, returning a result indexed only by k.
