Rref is the inert form of rref.
Rref returns rref without
evaluation.
It is used in conjonction with mod in Maple syntax mode to
find the row reduction to echelon form
of a matrix with coefficients in ℤ/pℤ (see
also 2.52.3).
Example, solve in ℤ/13ℤ
⎧ ⎨ ⎩ |

Input in Xcas mode :
Output :
you need to eval(ans()) to get :
and conclude that x=3%13 and y=3%13.
Input in Maple mode :
Output :
