Systems of polynomial equations
Continuing from my previous posts:
I represent the rotation as quaternion $[q_1, q_2, q_3, q_4]^T = [\mathbf{q}^T, q_4]^T$, instead of roll, pitch, yaw angles, then $\mathbf{R}_x = (2q_4^2 -1) \mathb …

Numerical solution for a system of multivariate polynomial equations
Hi all,
I have a system of 6th-order polynomial equations in 4 variables $q_1, q_2, q_3, q_4$ (i.e. polynomials with all the terms such as $q_1^6, q_2^6, q_2^4 q_3^2$):
$P_k(q_1, q_2, q_3, q_4) = 0$ …
