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.
