SVDSetUp#

Sets up all the internal data structures necessary for the execution of the singular value solver.

Synopsis#

#include "slepcsvd.h" 
PetscErrorCode SVDSetUp(SVD svd)

Collective

Input Parameter#

  • svd - the singular value solver context

Notes#

This function need not be called explicitly in most cases, since SVDSolve() calls it. It can be useful when one wants to measure the set-up time separately from the solve time.
