- 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 degreeslist2 = 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 commandPolygon[Sort[list1, arg(list1)]]. This command yields poly1 = 2.94.
- In order to sort a list of polynomials
Note: There is a workaround to sort lists of arbitrary objects which is explained in the Tutorial:Advanced List Sorting.
