Synopsis

• Optional inputs:
  • DegreeOrder => ..., default value null, specify Ascending, Descending, or null
  • MonomialOrder => ..., default value Ascending, specify Ascending or Descending monomial order

Description

i1 : rsort {4,2,3,1}

o1 = {4, 3, 2, 1}

o1 : List

i2 : R = QQ[a..d];

i3 : m = matrix{{a*b, c*d, a*d^3, b^3*c, 1_R}}

o3 = | ab cd ad3 b3c 1 |

             1      5
o3 : Matrix R  <-- R

i4 : rsort(m, DegreeOrder=>Ascending)

o4 = | b3c ad3 ab cd 1 |

             1      5
o4 : Matrix R  <-- R
