Sorts an index data set so that it becomes ascending.
Syntax
IndexSort(Index [ , RemoveDuplicates = TRUE ])
The syntax of the IndexSort function consists of the following parts:
Part |
Description |
|---|---|
Index |
A data series with indices or a data matrix with 2D indices. Permitted data structures are Data series und Data matrix. All real data types are permitted. If the argument is a list, then the function is executed for each element of the list and the result is also a list. |
RemoveDuplicates |
TRUE, if duplicates are to be removed from the index. Permitted data structures are Scalar value. Supported data types are Boolean value. If the argument is a list, then the first element in the list is taken. If this is also a list, then the process is repeated. If this argument is omitted, it will be set to the default value TRUE . |
Remarks
The result always has the data type 64-bit integer.
The result is a data series or a data matrix with the Index sorted in ascending order. A 2D index is sorted in ascending order when the indices are counted off by row; for example: { {0, 0}, {0, 1}, {0, 2}, {1, 0}, {1, 1}, {1, 2} }. Index must contain values greater than or equal to zero.
