#include "petscvec.h" PetscErrorCode VecStepBoundInfo(Vec X, Vec DX, Vec XL, Vec XU, PetscReal *boundmin, PetscReal *wolfemin, PetscReal *boundmax)Collective on Vec
| X | - vector with no negative entries | |
| XL | - lower bounds | |
| XU | - upper bounds | |
| DX | - step direction, can have negative, positive or zero entries |
| 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] |
