e.g when multiplying M1*M2 where M1=[A B ; C D], M2=[E F; G H] and A-H are all vectors I want MATLAB to return [A.*E+B.*G A.*F+B.*H ; C.*E+D.*G C.*F+D.*H] I can type out the formula for 2 matrices easily, but 10 matrices? It gets...
Rotating vectors using quaternions To rotate a vector, v, using quaternion math, represent the vector as [0, v] and represent the rotation by a quaternion, q. The vector is rotated according to Equation 2.31. (2.31)Rotq(v)≡qvq−1=v′ A series of rotations can be concatenated into ...
