Array Functions - Array Ops

These functions operate 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]. Except for arraytoimage, these functions support only 1-dimensional arrays. The arraytoimage function also supports 2-dimensional arrays. Many of these functions also work with an argument list consisting of numbers and pixel data of a CImage object.

Array Functions for General Array Operations
arrayindex, arrayindex_b	Returns the the linear index of multi-dimensional coordinates in a multi-dimensional array. This function is the inverse of arraycoord.
arraycoord	Returns the coodinate array for an offset index. This function is the inverse of arrayindex.
arraytoimage	Converts a 1- or 2-dimensional array to a 1- or 2-dimensional CImage object.
flatten	Flattens the numeric values of a general table into an array.
list	Lists the contents of an array.
reverse	Reverses a 1-dimensional array with regard to the order of the array indices.
series	Creates and returns a 1-dimensional array containing uniformly spaced numbers.
sort	Sorts the numbers of a 1-dimensional array into ascending order.
sortr	Sorts the numbers of a 1-dimensional array into descending order.
