% Rotate about a body axis to align a body vector with an inertial vector. 1. Begin with an initial quaternion 2. Rotate about a body-frame axis to align a body-frame vector with an inertial target vector 3. Return the new quaternion Will generate a plot if no outputs are requested. -------------------------------------------------------------------------- Form: [q,rotAngle,sepAngle] = QAlign( q0, uBAxis, uBVec, uITarget ); -------------------------------------------------------------------------- ------ Inputs ------ q0 (4,:) Beginning inertial to body quaternion uBAxis (3,1) Body-frame axis to rotate about uBVec (3,1) Body-frame vector to align uITarget (3,:) Inertial-frame vector to point at ------- Outputs ------- q (4,:) Resulting Inertial-to-Body quaternion after rotation rotAngle (1,:) Angle of rotation [rad] sepAngle (1,:) Separation angle between body vector and target [rad] --------------------------------------------------------------------------
