Hello! Not sure what you want -- but perhaps this helps. A : matrix ([a/w, b/x], [c/y, d/z]); num (A); => matrix([a/w,b/x],[c/y,d/z]) denom (A); => 1 matrixmap (num, A); => matrix([a, b], [c, d]) matrixmap (denom, A); => matrix([w, x], [y, z]) Most Maxima functions do not automatically process a list or matrix element by element. The functions map and matrixmap apply a function element by element. > Quand j'extrait un des éléments, il apparait bien sous forme de fraction, > mais toujours encadré par des crochets !! Hmm. From this, it appears your matrix is a nested matrix -- a matrix with elements that are also matrices. Is that intentional? Sorry, I can read a little French but I can't write it. Hope this helps!
