TaoADMMSetMisfitConstraintJacobian

Set the constraint matrix B for the TAOADMM algorithm. Matrix B constrains the z variable.

Synopsis

#include "petsctao.h" 
PetscErrorCode TaoADMMSetMisfitConstraintJacobian(Tao tao, Mat J, Mat Jpre, PetscErrorCode (*func)(Tao tao, Vec u, Mat J, Mat Jpre, PetscCtx ctx), PetscCtx ctx)

Collective

Input Parameters

• tao - the Tao solver context

• J - user-created misfit constraint Jacobian matrix

• Jpre - user-created misfit Jacobian constraint matrix for constructing the preconditioner, often this is J

• func - function pointer for the misfit constraint Jacobian update function

• ctx - application context for the regularizer constraint Jacobian

Calling sequence of func

• tao - the Tao context

• u - in current input solution

• J - the contribution to the misfit constraint Jacobian

• Jpre - the contribution to matrix from which to construct a preconditioner for the misfit constraint Jacobian

• ctx - the optional application context
