TaoADMMSetRegularizerConstraintJacobian#

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

Synopsis#

#include "petsctao.h" 
PetscErrorCode TaoADMMSetRegularizerConstraintJacobian(Tao tao, Mat J, Mat Jpre, PetscErrorCode (*func)(Tao, Vec, Mat, Mat, void *), void *ctx)

Collective

Input Parameters#

  • tao - the Tao solver context

  • J - user-created regularizer constraint Jacobian matrix

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

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

  • ctx - user context for the regularizer Hessian
