Hello- I am having trouble using transcendental extension for manipulation of rational functions. I would like to have a matrix with quolynomial entries. Is this possible in Singular? Thank you. Steve |

Sure you can do. See parameter and 4.10 matrix declariations e.g.: Code: ring Rt = (0,s,t),(x,y),lp; // s and t are transcendal parameters // define a 2x3 matrix with polynomial entries in x and y // having rational coefficients in Q(s,t) matrix m[2][3] = 2/t*x+1,1, xy, s/(t2-1),s/t*y,0; m; m[2,3] = -1; // new assignment print(m); |
