SortVectors()

Summary

Sorts an array of vectors in ascending order, based on the first vector.

 

Changes

Added to Version 6.0/2012.

 

Syntax

sort_array = SortVectors(array vecs [, array options])

 

Argument	Contents
vecs	The array of vectors to be sorted, based on the first vector

 

Option	Type	Contents
Omit Missing	Boolean	If "True"omits the elements in all the vectors when the first vector has a missing value; if "False" (the default) all elements of all the vectors will be included
Unique	Boolean	If "True" will return the elements where the first vector is unique; the default is "False"

 

Returns

A new array of vectors, with the elements in each vector sorted based on the first vector.

 

Notes

• The options array is an optional argument.

• Nulls are sorted to the beginning.

• The vectors in the array must be the same length, but can be of different types.

• For more information on vectors, see Vectors.

Example

a1  = {3.3, 2.2, 1.1}

a2 = {232,434,211}

v1 = a2v(a1)

v2 = a2v(a2)

vecs = SortVectors({v1,v2},)
