Mounting matrix 8*09a642b7SGe Gao is a 3x3 unitary matrix. A typical mounting matrix would look like 9*09a642b7SGe Gao [0, 1, 0; 1, 0, 0; 0, 0, -1]. Using this information, it would be 10*09a642b7SGe Gao easy to tell the relative positions among sensors as well as their 11*09a642b7SGe Gao positions relative to the board that holds these sensors. Identity matrix 12*09a642b7SGe Gao [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and device are perfectly 13*09a642b7SGe Gao aligned with each other. All axes are exactly the same. 14
