Sort Command

Sort[List]

Sorts a list of numbers, text objects, or points.

Note: Lists of points are sorted by x-coordinates.

Examples:

• Sort[{3, 2, 1}] gives you the list {1, 2, 3}.
• Sort[{"pears", "apples", "figs"}] gives you the list elements in alphabetical order.
• Sort[{(3, 2), (2, 5), (4, 1)}] gives you {(2, 5), (3, 2), (4, 1)}.

Sort[ <Values>, <Keys> ]

Sorts the first list Values according to the corresponding second list Keys.

Examples:

• In order to sort a list of polynomials list1 = {x^3, x^2, x^6} according to degree, create the dependent list of degrees list2 = Zip[Degree[a], a, list1]. After that, Sort[list1, list2] yields the requested list3 = {x^2, x^3, x^6}.
• In order to draw the polygon having as vertices the complex roots of x^{10}-1, sorted by their arguments, create list1 = {ComplexRoot[x^10-1]}, then use the command Polygon[Sort[list1, arg(list1)]]

Note: There is a workaround to sort lists of arbitrary objects which is explained in the Tutorial:Advanced List Sorting.
