| Description: | |
| This is mounting matrix for motion sensors. Mounting matrix | |
| is a 3x3 unitary matrix. A typical mounting matrix would look like | |
| [0, 1, 0; 1, 0, 0; 0, 0, -1]. Using this information, it would be | |
| easy to tell the relative positions among sensors as well as their | |
| positions relative to the board that holds these sensors. Identity matrix | |
| [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and device are perfectly | |
| aligned with each other. All axes are exactly the same. |
