SlepcInitialize#

Initializes the SLEPc library. SlepcInitialize() calls PetscInitialize() if that has not been called yet, so this routine should always be called near the beginning of your program.

Synopsis#

#include "slepcsys.h" 
PetscErrorCode SlepcInitialize(int *argc,char ***args,const char file[],const char help[])

Collective on MPI_COMM_WORLD or PETSC_COMM_WORLD if it has been set

Input Parameters#

  • argc - count of number of command line arguments

  • args - the command line arguments

  • file - [optional] PETSc database file, defaults to ~username/.petscrc (use NULL for default)

  • help - [optional] Help message to print, use NULL for no message

Fortran Notes#

Fortran syntax is very similar to that of PetscInitialize()
