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
