petscmaster 20170623
Documentation: Changes: 2.2.0
General:
 Changed petscengine.h to petscmatlab.h

Changed PetscOptionsEList() to return the index of the string
selected by the user (error if user enters impossible string)
Vec:
 VecLoad() has a new argument giving the Vector type to be created
Mat:

If you use MAT_SYMMETRIC as option for MatSetOption() you will likely
need to also use the option MAT_SYMMETRY_ETERNAL otherwise at the
next MatAssembly the matrix will likly lose the symmetry flag.
 Added MatISGetLocalMat() to allow preallocating the local matrix.
PC:
KSP:
 changed unmodifiedGramSchmidt name to classicalGramSchmidt everywhere.

Eliminated KSPGMRESIROrthogonalize() now have
KSPGMRESSetCGSRefinement() to decide when to use iterative refinement

The SLES object has been removed from PETSc. All of this options are
available via the KSP object. For example, sles_view_binary
>ksp_view_binary, SLESCreate()>KSPCreate() The calling
sequences SLESSetUp(sles,b,x) should be replaced with
KSPSetRhs(ksp,b) KSPSetSolution(ksp,x) KSPSetUp(ksp). Similarly
SLESSolve(sles,b,x) should be replaced with KSPSetRhs(ksp,b)
KSPSetSolution(ksp,x) KSPSolve(ksp)
 removed its argument from KSPSolve. Obtain the number of iterations via KSPGetIterationNumber()
SNES:

SNESSolve() no longer returns number of iterations, use
SNESGetIterationNumber() to get the number of iterations
required
TS:
DMMG:

Added support for dmmg_galerkin and DMMGSetUseGalerkin() for
nonlinear problems (not sequential only)
SYS:
 added new PETSC_VIEWER_MATLAB for saving variables to Matlab .mat files

eliminated PetscViewerXXXXType and PetscViewerXXXSetType() replaced
with PetscViewerFileType and PetscViewerSetFileType()

PETSC_BINARY_RDONLY,PETSC_BINARY_WRONLY,PETSC_BINARY_CREATE becomes
PETSC_FILE_RDONLY,PETSC_FILE_WRONLY,PETSC_FILE_CREATE
