Array Functions

Array Functions - Math

The functions below perform statistical calculations on a lua table containing numeric values but no string values, string keys, or sub-tables. This type of table is called an array, or indexed array, since the elements may be accessed by their index, as in x[5]. Many of these functions also work with an argument list consisting of numbers and pixel data of a CImage object.
