Update linear operator.
This function updates the linear operator at new iterations.
[in] | x | is the new iterate. |
[in] | flag | is true if the iterate has changed. |
[in] | iter | is the outer algorithm iterations count. |

Apply linear operator.
This function applies the linear operator to a vector.
[out] | Hv | is the output vector. |
[in] | v | is the input vector. |
[in] | tol | is a tolerance for inexact linear operator application. |

Apply adjoint of linear operator.
This function applies the adjoint of a linear operator to a vector. Default behavior assumes operator is self-adjoint.
[out] | Hv | is the output vector. |
[in] | v | is the input vector. |
[in] | tol | is a tolerance for inexact linear operator application. |
