Adjoint matrix (my function): ok with numbers but not symbolics
hi,
in the code in this program the function adj(m) works well with numbers like Code: adj([1,2],[3,4]) Code: adj([a,b],[c,d]) Why? The need to have this function is because the new adjoint_matrix() in the CAS is, as it must be, more detailed, and it returns characteristic polynomial of A and the comatrix o A-xI, i.e. Code:
Code: [[d, -b],[-c,a]] Any help, please, using (or not) the new adjoint_matrix()? Salvo ∫aL√0mic (IT9CLU) :: HP Prime 50g 41CX 71b 42s 39s 35s 12C 15C - DM42, DM41X - WP34s Prime Soft. Lib |
