Hi Ravi, I did ask you some question regarding newton method sometime ago..  Now I have fixed the problem and I also wrote 2 looping code (ff1 and ff2) to evaluate the modified Bessel function of the first kind and call them in the newton code.  But I dont't understand why it gives the error mes

Hi Rolf, I would like to extend the problem that I asked you before regarding the newton method using 4 functions with 4 parameters.  My functions involve the modified bessel function of the first kind which I can type them without any problem. The big problem is the Jacobian matrix. I use Mapl
