[petsc-users] DMDAVecRestoreArrayF90

[Barry Smith]

   PETSc 2.23 introduced some incompatibilities in the Fortran bindings with previous versions of PETSc. 

   As part of upgrading Fortran code for use with PETSc 2.23 the suffix F90 should be removed from all PETSc Fortran calls; for routines such as DMDAVecGetArrayF90() no other changes are needed to the function call. The array arguments remain Fortran pointers to arrays.
