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#
bv - basis vectors
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.
