Transformations/Axes

Description

The Euler Angles to Direction Cosine Matrix block converts the three Euler rotation angles into a 3-by-3 direction cosine matrix (DCM). The DCM matrix performs the coordinate transformation of a vector in inertial axes into a vector in body axes . The order of the axis rotations required to bring into coincidence with is first a rotation about through the roll angle to axes . Second a rotation about through the pitch angle to axes , and finally a rotation about through the yaw angle to axes.

Combining the three axis transformation matrices defines the following DCM.
