But i could't get stable estimated gain matrix for every sample file(sample one device for 50 times and get one file every time,every sample file contains about 100 records of x,y,z),some of my estimated gain matrix :

- file 1:  $$$$\left [ \begin{array}{ccc} 0 & 0 & 0 \\ 0 & 0 & 0 \\ 0 & 0 & 156.762112 \\ \end{array} \right ]$$$$
