SVDTRLanczosSetOneSide
Indicate if the variant of the Lanczos method to be used is one-sided or two-sided.
Synopsis
#include "slepcsvd.h"
PetscErrorCode SVDTRLanczosSetOneSide(SVD svd,PetscTruth oneside)
Collective on SVD
Input Parameters
| svd | - singular value solver
|
| oneside | - boolean flag indicating if the method is one-sided or not
|
Options Database Key
-svd_trlanczos_oneside <boolean> - Indicates the boolean flag
Note
By default, a two-sided variant is selected, which is sometimes slightly
more robust. However, the one-sided variant is faster because it avoids
the orthogonalization associated to left singular vectors.
