VecSetRandomNormal#

Sets all components of a vector to normally distributed random values.

Synopsis#

#include "slepcvec.h" 
PetscErrorCode VecSetRandomNormal(Vec v,PetscRandom rctx,Vec w1,Vec w2)

Logically Collective

Input Parameters#

v - the vector to be filled with random values
rctx - the random number context (can be NULL)
w1 - first work vector (can be NULL)
w2 - second work vector (can be NULL)

Notes#

Fills the two work vectors with uniformly distributed random values (VecSetRandom()) and then applies the Box-Muller transform to get normally distributed values on v.
