[Maxima] how to generate matrix by existed matrices

[Barton Willis]

Maybe 'addcol' does what you want:

 (%i1) A:matrix([1,2]);
 (%o1) matrix([1,2])

 (%i2) B:matrix([3,4]);
 (%o2) matrix([3,4])

 (%i5) C: addcol(transpose(A),transpose(B));
 (%o5) matrix([1,3],[2,4])

 (%i6) determinant(C);
 (%o6) -2

Also there is a function 'addrow.'
