For any matrix in the rotation group SO₃, we give the explicit expression for its axis and angle of rotation without computing eigenvectors. The formulas depend only on the entries of the matrix, ...
Abstract: Attitude states are critical parameters in the control, navigation, and guidance of aerial robotics. Various models, including Euler angles, rotation matrices, and quaternions, are used to ...
Hello, first of all, I'd like to appreciate for developing wonderful package which deals with very important symmetry issues. I'm not very familiar with crystallographic so Please forgive me if I'm ...
Abstract: Accurate estimation of rotation angles in polarimetric imaging is critical for high-precision polarimetric measurements. While existing least-squares-based methods avoid complex instrument ...
Figure 1: HB-NBP molecule. Finally, the molecule was mounted on top of an atomic defect bound to one elbow (see Fig. 3). Once mounted concentrically on its atomic pinning centre, HB-NBP was ...
This repository contains a program written in m68k assembly, created using the EASy68k development environment and tested with the EASy68k simulator. The program demonstrates 2D matrix rotation by ...
