petsc-3.7.7 2017-09-25
   
    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
