Description
The Direction Cosine Matrix to Rotation Angles block converts
the first, second, and third rotation angles of a 3-by-3 direction cosine matrix (DCM)
into the rotation angles R1, R2, and R3, respectively. The DCM matrix performs the
coordinate transformation of a vector in inertial axes into a vector in body axes. The
block Rotation Order parameter specifies the order of the block
output rotations. For example, if Rotation Order has a value of
ZYX
, the block outputs are in the rotation order
z-y-x
(psi theta phi).
