Determinant of a matrix in
/p : det
det takes as argument a matrix A with coefficients in
Z/pZ.
det returns the determinant of this matrix A.
Computation are done in
/p by Gauss reduction.
Input :
det([[1,2,9]%13,[3,10,0]%13,[3,11,1]%13])
Or :
det([[1,2,9],[3,10,0],[3,11,1]]%13)
Output :
5%13
hence, in
/13, the determinant of
A = [[1, 2, 9],[3, 10, 0],[3, 11, 1]] is 5%13 (in
, det(A)=31).
