Rigid body orientation什么意思
Weburation of a rigid body that arise from integrating a six-dimensional twist con-sisting of the body's angular and linear velocities. This representation follows from the Chasles{Mozzi theorem which states that every rigid-body displace-ment can be obtained by a nite rotation and translation about a xed screw axis. WebEigenvalue Equation Lets say we have a known matrix M and we want to know if there is any vector x and scalar s such that 𝐌𝐱= 𝐱 This is known as an eigenvalue equation, and for a NxN matrix, there should be up to N eigenvectors 𝐱𝑖 and N eigenvalues 𝑖 that satisfy the equation If M is a symmetric matrix (i.e., 𝐌𝑇=𝐌) then all of the eigenvalues
