PetscRandomGetValue

Synopsis

#include "petscsys.h" 
PetscErrorCode  PetscRandomGetValue(PetscRandom r,PetscScalar *val)

Intput Parameter

Output Parameter

Notes

When PETSc is compiled for complex numbers this returns a complex number with random real and complex parts. Use PetscGetValueReal() to get a random real number.

To get a complex number with only a random real part, first call PetscRandomSetInterval() with a equal low and high imaginary part. Similarly to get a complex number with only a random imaginary part call PetscRandomSetInterval() with a equal low and high real part.

Example of Usage

      PetscRandomCreate(PETSC_COMM_WORLD,&r);
      PetscRandomGetValue(r,&value1);
      PetscRandomGetValue(r,&value2);
      PetscRandomGetValue(r,&value3);
      PetscRandomDestroy(&r);
