Syntax
The MAKEARRAY function syntax has the following arguments and parameters:
rows
The number of rows in the array. Must be greater than zero.
cols
The number of columns in the array. Must be greater than zero.
lambda
A LAMBDA that is called to create the array. The LAMBDA takes two parameters:
row
The row index of the array.
col
The column index of the array.
Tip
Before using this function, you need to turn on the allowDynamicArray option
Basic Usage
var data = {
values: {
1: { 1: "Examples:" },
3: { 1: "Example 1: Create a 2D array representing a simple multiplication table" },
4: { 1: "Formula:" },
5: { 1: "Result:" },
9: { 1: "Example 2: Create a random list of values" },
10: { 1: "Rows:", 2: 10, 3: "Cols:", 4: 5 },
11: { 1: "Formula:" },
12: { 1: "Result:" },
},
formulas: {
4: { 2: "FORMULATEXT(C6)" },
5: { 2: "MAKEARRAY(3,3,LAMBDA(r,c,r*c))" },
11: { 2: "FORMULATEXT(C13)" },
12: { 2: 'MAKEARRAY(C11,E11,LAMBDA(row,col,CHOOSE(RANDBETWEEN(1,3),"Red","Blue","Green")))' },
},
