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
