[petsc-users] obtaining estimated Hessian in BQNLS

[Stefano Carli]

Dear PETSc developers,

I'm using PETSc version 3.14.1 coupled to a Fortran code, and I was wondering if there is a way of obtaining in output, possibly at each iteration, the estimated Hessian matrix for the BQNLS method.

Thank you in advance and best regards,
Stefano Carli
