MAKEARRAY

MAKEARRAY(rows, cols, lambda(row, col))

Returns the array calculated by applying a LAMBDA function.

rows	The number of rows in the array.
cols	The number of columns in the array.
lambda	A nested LAMBDA function that takes two parameters.
row	The row index of the array.
col	The column index of the array.

REMARKS

* This function was added in Excel 2024.
* This function can create a Dynamic Array Formula.
* This function uses the LAMBDA function.
* This LAMBDA function must take two parameters.
* The parameter names must not contain any numbers.
* If "row" < 1, then #VALUE! is returned.
* If "col" < 1, then #VALUE! is returned.
* This function was first released in July 2021.

1 - Create a 1x1 array using a formula that returns the row number.
2 - Create a 1x1 array using a formula that returns the column number.
3 - Create a 1x1 array using a formula that adds the row number and the column number together.
4 - Create a 2x2 array using a formula that multipies the row number and the column number together. The array that is returned is calculated from (1*1, 1*2 ; 2*1, 2*2).
