BVSetRandomNormal
Set the columns of a BV to random numbers with a normal distribution.
Synopsis
#include "slepcbv.h"
PetscErrorCode BVSetRandomNormal(BV bv)
Logically Collective
Input Parameter
Notes
All active columns (except the leading ones) are modified.
Other functions such as BVSetRandom(), BVSetRandomColumn(), and BVSetRandomCond()
produce random numbers with a uniform distribution. This function returns values
that fit a normal distribution (Gaussian).
Developer Notes
The current implementation obtains each of the columns by applying the Box-Muller
transform on two random vectors with uniformly distributed entries.
