Synopsis

#include "petscvec.h"  
PetscErrorCode VecStepBoundInfo(Vec X, Vec DX, Vec XL, Vec XU, PetscReal *boundmin, PetscReal *wolfemin, PetscReal *boundmax)

Collective

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 Parameters

• 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] + boundmaxDX[i] <= XL[i] or XU[i] <= X[i] + boundmaxDX[i]

Note

For complex numbers only compares the real part
