# 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 Note

Fortran syntax is very similar to that of PetscInitialize()
