Quote:Why don't you write a CAS program ? oh, well (it is not a bug, Tim) In 2015 we hadn't adjoint_matrix()... Thank you! Now is more and more simple. I'm rewriting the program as you suggest. Only a little difference: adjoint_matrix([[1,2],[4,3]])[2,2] returns [[3,2],[4,1]] and my adj([[1,2],[4,3]]) returns [[3,2],[4,1]], that's the first result multiplied by 1 ... Also with [[a,b],[c,d]] I get the difference * 1... ∫aL√0mic (IT9CLU) :: HP Prime 50g 41CX 71b 42s 39s 35s 12C 15C  DM42, DM41X  WP34s Prime Soft. Lib
