[petsc-users] Question about using MatSNESMFWPSetComputeNormU

[최경준]

Hi, I'm trying to set my SNES matrix-free with Walker & Pernice way of
computing h value.

I found above command (MatSNESMFWPSetComputeNormU) but my fortran compiler
couldn't fine any reference of that command.

I checked Petsc changes log, but there weren't any mentions about that
command.

Should I have to include another specific header file?

Thank you always.
