Scilab Function udh - add short decription here
Calling Sequence
- H = udh(X)
Parameters
- X
: real vector, variables of the problem
- H
: real matrix, hessian
Description
udh evaluates the Hessian matrix of the objective function of the
current SIF problem (see usetup) at the point X in
the case where the only possible constraints are bound constraints.
This Hessian matrix is stored as a dense matrix.
Examples
sifdecode(get_sif_path()+'sif/AKIVA.SIF',TMPDIR+'/AKIVA')
buildprob(TMPDIR+'/AKIVA')
[X,BL,BU]=usetup(TMPDIR+'/AKIVA/OUTSDIF.d');
h=udh(X)
X=[-0.053109827466;-0.237575444849];
h=udh(X)
