Rotate vector by quaternion
Aerospace Blockset / Utilities / Math Operations
The Quaternion Rotation block rotates a vector by a quaternion. Aerospace Blockset™ uses quaternions that are defined using the scalar-first convention. For the equations used for the quaternion, vector, and rotated vector, see Algorithms.
Quaternions in the form of [q0, r0, ..., q1, r1, ... , q2, r2, ... , q3, r3, ...], specified as a quaternion or vector of quaternions.
Vector or vector of vectors in the form of [v1, u1, ... , v2, u2, ... , v3, u3, ...].
vec_rot— Rotated quaternion
Rotated vector or vector of rotated vectors.
The quaternion has the form of
The vector has the form of
The rotated vector has the form of
