PetscRandomSetSeed#

Sets the random seed. You MUST call PetscRandomSeed() after this call to have the new seed used.

Synopsis#

#include "petscsys.h" 
PetscErrorCode PetscRandomSetSeed(PetscRandom r, unsigned long seed)

Not collective

Input Parameters#

r - The random number generator context
seed - The random seed

Usage#

      PetscRandomSetSeed(r,a positive integer);
      PetscRandomSeed(r);
      PetscRandomGetValue() will now start with the new seed.

      PetscRandomSeed(r) without a call to PetscRandomSetSeed() re-initializes
      the seed. The random numbers generated will be the same as before.
