Thanks very much! I am, of course, nobody in particular. > Bien que j'ai résolu mon problème, je m'interroge sur la pertinence de ce > comportement. A quoi sert alors la fonction row(M,i), s'il suffit de la > notation > 'ma[i]' pour extraire une ligne d'une matrice ??? row(M, i) => returns a matrix M[i] => returns a list So these are a little bit different. (In Maxima, lists and matrices are distinct -- a list is not a 1-row matrix.) The representation of a matrix in Maxima is very naive -- a matrix is just a list of lists (i.e., a list of rows). This makes M[i] => row very easy, but there is no equally simple notation to obtain a column. We have discussed matrix representation on the Maxima mailing list, so something might be changed in the not-too-distant future. All the best, and my apologies for not writing in the official language of the list.
