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 \mathrm{\mathsf{ x^{10}-1 }}, sorted by their arguments, create list1 = {ComplexRoot(x^10-1)}, then use the command Polygon(Sort(list1, arg(list1))). This command yields poly1 = 2.94.


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