TaoADMMSetRegularizerHessianRoutine

Sets the user-defined regularizer Hessian call-back function, to be used for subsolverZ.

Synopsis

#include "petsctao.h"

Collective

Input Parameters

• tao - the Tao context

• H - user-created matrix for the Hessian of the regularization term

• Hpre - user-created matrix for building the preconditioner of the Hessian of the regularization term

• func - function pointer for the regularizer Hessian evaluation

• ctx - application context for the regularizer Hessian

Calling sequence of func

• tao - the Tao context

• u - in current input solution

• H - output, the contribution to the Hessian matrix

• Hpre - an optional contribution to an alternative matrix with which the preconditioner is to be constructed

• ctx - the optional application context
