I's just wondering if you'd had a chance to do the Fortran interface for SNESSetUpdate?<br></div></div></blockquote><div><br></div><div>I don't know how to do this one since we overhauled our Fortran callbacks.

Also what would you guys recommend for interrupting SNESSolve? For example when the solution vector is outside the range for the RHS function that can be evaluated.<br></div></div></blockquote><div><br></div><div>I think the new scheme is to return a NaN.

Hello,<br>
is there an index of the PETSc operations (e.g. mathematical on Vec's<br>
and Mat's) that do NOT overwrite the operands?<br>
I understand in-place operations are more efficient, but they make it<br>
harder to reason about the program's operation.<br>
