Hi!
I have two small corrections for you...
In the long data list supplied for exercise 2 in H5 there are two errors:
Force residual should be F = 415.1071
Moment residual M = 4.0545e+03
and the Jacobian has been transposed in the presentation so it should be
J=[-1108 -740; -21113 356661]
All other data is correct, at least for the time being =) Hope your making progress!
Cheers!
