[petsc-users] Is it necessary to call MatAssembly*() with MatSetValue()

Hi, By `find` and `grep`, I find that in many PETSc examples `MatAssembly*()` are called after `MatSetValue()`. But in the C/Fortran API manual, the man page of `MatAssembly*()` does not say it is necessary for `MatSetValue()`. And the man page of `MatSetValue()` does not say it is a must to call `MatAssembly*()` afterwards. Is the man page of `MatSetValue()` up-to-date, or it lacks the reminder for the necessity of calling `MatAssembly*()`? Best regards, C.-Y. GAO
