SCAN

Progressively applies a LAMBDA function to each element in an array and returns an array of all intermediate values.

Enter the formula as an array formula. Hint: enter formula using keys Ctrl + Shift + Enter.

Syntax

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

Initial value: Optional initial value of the accumulator.

Array: The array to be scanned.

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.

Examples

Example

The following data will be used as example

	A	B	C
1	Maths	Physics	Biology
2	47	67	33
3	36	68	42
4	40	65	44
5	39	64	60
6		38	43
7	47	84	62
8	29	80	51
9	27	49	40
10	57	49	12
11	56	33	60
12	57
13	26

The formula =SCAN(0;A2:C2;LAMBDA(a;v;a+v)) returns the array

114

147

which correspond to A2, A2+B2 and A2+B2+C2, respectively.
