cidh

Evaluate individual problem function Hessian

Calling Sequence

Hi = cidh(x,i)

Parameters

x

real vector, the variable

i

integer, see below

Hi

matrix,the Hessian of the i-th function

Description

cidh Evaluate individual problem function Hessian x. The value of i specifies the function:

i=0 -> objective function,

i>0 -> i-th constraint function.

Hi=cidh(x,i) returns the Hessian of the i-th function in Hi, stored as a full matrix.

Examples

sifdecode(get_sif_path()+'sif/BT1.SIF',TMPDIR+'/BT1')
buildprob(TMPDIR+'/BT1')
[x,bl,bu,v,cl,cu,equatn,linear] = csetup(TMPDIR+'/BT1/OUTSDIF.d');
Hi = cidh(x,1)
