Inverse takes as argument a matrix with coefficients in ℤ/pℤ.
Inverse returns inverse without evaluation. 
It is used in conjonction with mod in Maple syntax mode to 
find the inverse of a matrix with coefficients in ℤ/pℤ.
Input in Xcas mode :
Output :
you need to eval(ans()) to get :
 
which is the inverse of A=[[1,2,9],[3,10,0],[3,11,1]] in ℤ/13ℤ.
Input in Maple mode :
Output :
