Rotation Angles to Direction Cosine Matrix - Convert rotation angles to direction cosine matrix

Library

Utilities/Axes Transformations

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.
