Singular Manual: det

  | ### 5.1.21 det `Syntax:` `det (` intmat_expression `)` `det (` matrix_expression `)` `det (` module_expression `)` `Type:` int, resp. poly `Purpose:` returns the determinant of a square matrix. A module is considered as a matrix. The applied algorithms depend on type of input. If the input is a module or matrix with symbolic entries the Bareiss algorithm is used. In the other cases the chinese remainder algorithm is used. For large sparse problems the input as a module has advantages. `Example:`
        ring r=7,(x,y),wp(2,3);
        matrix m[3][3]=1,2,3,4,5,6,7,8,x;
        det(m);
      ==> -3x-1
See intmat; matrix; minor.
