 Sort
 sort numeric data Calling Sequence Sort(X, options) Parameters

 X - options - (optional) equation(s) of the form option=value where option is one of order or unique; specify options for the Sort function Description

 • The Sort command sorts the elements of X according to their numeric values.
 • The first parameter X is the data set (typically an Array or a list). Options

 The options argument can contain one or more of the options shown below.
 • order=ascending or descending -- Indicates whether the elements of X should be sorted in the ascending or descending order. The default value is order=ascending.
 • unique=truefalse -- If this option is set to true, all multiple occurrences of elements from X will be removed. The default value is unique=false. Note that if this option is set to unique=true then all elements of X must be of type float. Notes

 • Although the Sort command accepts non-numeric data, maple must be able to compute floating-point values for all elements in X. If the unique option is set to unique=true all elements in X must be of type numeric.
 • The Sort command creates a copy of the original data. Examples
