Array.$$(Function|Array of Functions[,param1,param2,...])

This returns the result of each row of the Array being operated on by the function or array of functions passed. The parameters provided following the function/function array is passed to the function with each row as the first parameter. Used for aggregate functions or functions that apply on each row (such as a spreadsheet calculation).

For example,
a=|4,4,1..10|

{| class="wikitable"|-
| 1 || 2 || 3 || 4
|-
| 5 || 6 || 7 || 8
|-
| 9 || 10 || 1 || 2
|-
| 3 || 4 || 5 || 6
|}

a.$$(SUM)

{| class="wikitable"|-
| 10
|-
| 26
|-
| 22
|-
| 18
|}
gives row wise sums of each row.
