| 49 | |||
| 50 | Notes: | ||
| 51 | The state indicates that the dense system is in an initial state (raw), | ||
| 52 | in an intermediate state (such as tridiagonal, Hessenberg or | ||
| 53 | Hessenberg-triangular), in a condensed state (such as diagonal, Schur or | ||
| 54 | generalized Schur), or in a truncated state. | ||

| 56 | The state is automatically changed in functions such as `DSSolve()` or `DSTruncate()`. | ||
| 57 | This function is normally used to return to the raw state when the | ||
| 58 | condensed structure is destroyed, or to indicate that `DSSolve()` must | ||
| 59 | start with a problem that already has an intermediate form. | ||

| 409 | |||
| 410 | For matrices `DS_MAT_T` and `DS_MAT_D`, this function will return a `Mat` object | ||

| 865 | When the `DS` has been created with a communicator with more than one process, | ||

| 1041 | It computes a translation of a Krylov decomposition in order to extract | ||
| 1042 | eigenpair approximations by harmonic Rayleigh-Ritz. | ||
| 1043 | The matrix is updated as $A + gb^*$ where $g = (A-\tau I)^{-*}b$ and | ||
| 1044 | vector $b$ is assumed to be $\beta e_n^*$. | ||
| 1045 | |||
| 1046 | The $\gamma$ factor is defined as $\sqrt{1+g^*g}$ and can be interpreted as | ||
| 1047 | the factor by which the residual of the Krylov decomposition is scaled. | ||
| 1048 | |||
| 1049 | If the `recover` flag is activated, the computed translation undoes the | ||
| 1050 | translation done previously. In that case, parameter `tau` is ignored. | ||
