sortColumns(...,DegreeOrder=>...) -- specify Ascending, Descending, or null

Usage:

sortColumns(...,DegreeOrder=>x)
Inputs:
- x, a symbol, either Ascending, Descending, or null
Consequences:
- If x is not null, first order the columns of the matrix in ascending or descending degree (depending on x). If x is null, then only use the monomial order in the sort

Caveat

This option only works for sorting columns of a matrix, not the elements of a list

Functions with optional argument named DegreeOrder:

rsort(...,DegreeOrder=>...) -- specify Ascending, Descending, or null
sort(...,DegreeOrder=>...) -- specify Ascending, Descending, or null
sortColumns(...,DegreeOrder=>...) -- specify Ascending, Descending, or null

Further information

Default value: null
Function: sortColumns -- permutation giving sort order
Option key: DegreeOrder -- an optional argument
