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.
