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.
