TSAlphaGetParams
gets the algorithmic parameters for TSALPHA 
Synopsis
#include "petscts.h"   
PetscErrorCode  TSAlphaGetParams(TS ts,PetscReal *alpha_m,PetscReal *alpha_f,PetscReal *gamma)
Not Collective
Input Parameter
|  | ts | - timestepping context | 
|  | \alpha_m | - algorithmic parameter | 
|  | \alpha_f | - algorithmic parameter | 
|  | \gamma | - algorithmic parameter | 
Note
Use of this function is normally only required to hack TSALPHA to
use a modified integration scheme. Users should call
TSAlphaSetRadius() to set the high-frequency damping (i.e. spectral
radius of the method) in order so select optimal values for these
parameters.
