REDUCE

Applies a custom LAMBDA function to each element in a given array and accumulates results to a single value.

ໄວຍາກອນ

=REDUCE([Initial value]; Array; Formula)

Initial value: Optional initial value of the accumulator.

Array: The array to be reduced.

Formula: a LAMBDA function that will be called on each cell of the array.

The LAMBDA function requires two variables: an accumulator (e.g., a) and the array element value (v), and must be structured as follows:

LAMBDA (a, v, a + f (v))

where f(v) is a function of the individual cells of the array.

The formula =REDUCE(100000;A2:A13;LAMBDA(a;v; a + v*v)) returns 120715, which is 100000 added to the sum of the squares of the Math column.
