[ADOL-C] singularity

Hi Giang,

this means that the system matrix is singular, so in the current setting
it is not possible to compute a solution of your system using
the LU factorization.

Therefore, also a perturbation of your initial values probably would not help.

It seems that this is more of a general problem.

Hope, this helps?

Best regards

Andrea
