| wood_inv_solve | Compute the inverse approximate Hessian of the majorization using the Woodbury inversion formula. 'wood_inv_solve' computes the inverse of the Hessian term of the majorization of the proximity function using the Woodbury formula. The function 'mmqn_step' invokes 'wood_inv_solve' instead of ddg if the argument 'woodbury=TRUE'. This should be used when p << n. |
