SlepcInitialize#

Initializes the SLEPc library. SlepcInitialize() calls PetscInitialize() if it has not been called yet, so this function 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
help - [optional] Help message to print, use NULL for no message

Note#

Works in the same way as PetscInitialize(), but in addition initializes SLEPc. The same considerations apply with respect to command line options and environment variables.

Fortran Notes#

In Fortran this routine can be called with

       call SlepcInitialize(ierr)

       call SlepcInitialize(file,ierr)

or

       call SlepcInitialize(file,help,ierr)

If your main program is C but you call Fortran code that also uses SLEPc you need to call SlepcInitializeFortran() soon after calling SlepcInitialize().
