Table Functions
Table functions do math and other operations on numeric data stored in a Lua table used as an array. These functions are global so they can be used without creating any class object. All functions begin with a capital "T" followed by a capitalized name, like TSort or TMean.
These commands work on Lua tables as well as objects of the following classes: CImage, CArray, and CMatrix. Collectively, these are referred to as "data collections" in the descriptions below.
