Hi Olaf,

Dne 19. 11. 19 v 12:04 Olaf Till napsal(a):

My guess is that your custom dfdp still has some error (I didn't
check).

Thanks a lot for your patience. Of course I had wrong order of p elements in my dfdp. The custom precisely calculated jacobian yields better results than the finite differences method now, consistent with all the other cases in my project.

Once more thank you.

Best regards,

Pavel.
