Description
The Rotation Angles to Direction Cosine
Matrix block determines the direction cosine matrix (DCM) from a given
set of rotation angles, R1, R2, and R3, respectively the first, second,
and third rotation angles. The output is a 3-by-3 DCM that performs
the coordinate transformation of a vector in inertial axes into a
vector in body axes.
Dialog Box
- Rotation Order
Specifies the input rotation order for three rotation angles.
From the list, select ZYX, ZYZ, ZXY, ZXZ, YXZ, YXY, YZX, YZY, XYZ, XYX, XZY,
or XZX. The default is ZYX.
