I want program for show determiner on the matrix not used det(a) on the formal. For e.g if i run matrix after the Gauss Elimination and show (x (1.2,3)) after that show me determiner on the Diagonal matrix. I write a few code but it's wrong however i want general code for all matrix not only 3*3 or 4*4. i want use for(n*n) matrix. thanks

masoud - why not post the code that you have written (to find the determinant of a matrix) so that we can comment on what may be causing a problem?
