See below
Synopsis
#include "petscvec.h"
PetscErrorCode VecStepBoundInfo(Vec X, Vec DX, Vec XL, Vec XU, PetscReal *boundmin, PetscReal *wolfemin, PetscReal *boundmax)
Collective on Vec
Input Parameters
| X | - vector with no negative entries
|
| XL | - lower bounds
|
| XU | - upper bounds
|
| DX | - step direction, can have negative, positive or zero entries
|
Output Parameter
| boundmin | - (may be NULL this it is not computed) maximum value so that XL[i] <= X[i] + boundmax*DX[i] <= XU[i]
|
| wolfemin | - (may be NULL this it is not computed)
|
| boundmax | - (may be NULL this it is not computed) minimum value so that X[i] + boundmax*DX[i] <= XL[i] or XU[i] <= X[i] + boundmax*DX[i]
