Run the command by entering it in the MATLAB Command Window.Description. r = vrrotvec (a,b) calculates a rotation needed to transform the 3D vector a to the 3D vector b. r = vrrotvec (a,b,options) calculates the rotation with the default algorithm parameters replaced by values defined in options. Description. Takes input of two 3-by-1 vectors and returns a virtual world rotation (specified as a four-element vector defining axis and angle) that is needed to transform the first input vector to the second input vector. Oct 01, 2021 · Now you can use the this formula to get the rotation matrix. Similarly, you can get an axis perpendicular to V 1 and V 2 by using the cross product. The angle of rotation is given by the scalar (dot) product of the vectors. In case V 1 and V 2 are parallel, you can choose any vector in the perpendicular plane and rotate 180 ∘. hail mary by andy weir xa
