Inverse takes as argument a matrix with coefficients in ℤ/pℤ.
Inverse returns inverse without evaluation.
It is used in conjunction with mod in Maple syntax mode to
find the inverse of a matrix with coefficients in ℤ/pℤ.

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.
