SortIdx2 Function

Sorts the items in argument 1 but instead of returning the actual sorted data the function returns the indexes of the sorted values into the original array. The method of sorting depends on the data type as follows:

string	Alphabetic
real	Numeric
complex	Numeric - uses magnitude

Use this function instead of SortIdx in new code. The original function sorted numeric values from high value to low value which is the opposite to what might usually be expected.

Arguments

Number	Type	Compulsory	Default	Description
1	any array	Yes		Items to sort
2	string	No	'forward'	Sort direction

Argument 2

Sort option, value either 'forward' or 'reverse'. 'forward' for numeric data means lowest values first.

Returns

Return type: real array

An array of indexes into the input array, sorted by the method specified in argument 2.
