Convert rotation angles to direction cosine matrix
Utilities/Axes Transformations
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. For example, the
default rotation angle order ZYX
represents a sequence where R1 is
z-axis rotation (yaw), R2 is y-axis rotation
(pitch), and R3 is x-axis rotation (roll). Use the Rotation
Order parameter to change the sequence.
The output is a 3-by-3 DCM that performs coordinate transformations based on rotation angles.
Specifies the input rotation order for three rotation angles.
