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
NULLfor 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().
