6*4882a593SmuzhiyunDescription:
7*4882a593Smuzhiyun		This is mounting matrix for motion sensors. Mounting matrix
8*4882a593Smuzhiyun		is a 3x3 unitary matrix. A typical mounting matrix would look like
9*4882a593Smuzhiyun		[0, 1, 0; 1, 0, 0; 0, 0, -1]. Using this information, it would be
10*4882a593Smuzhiyun		easy to tell the relative positions among sensors as well as their
11*4882a593Smuzhiyun		positions relative to the board that holds these sensors. Identity matrix
12*4882a593Smuzhiyun		[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and device are perfectly
13*4882a593Smuzhiyun		aligned with each other. All axes are exactly the same.
