M |
3-by-3 matrix to project into SO(3). |
This function uses the process detailed in Section 3.1 of moakher02 to project an arbitrary 3-by-3 matrix into SO(3). More specifically it finds the closest orthogonal 3-by-3 matrix with determinant one to the provided matrix.
Projection of M into SO(3).

#Project an arbitrary 3x3 matrix into SO(3) M<-matrix(rnorm(9), 3, 3) project.SO3(M) #Project a sample arithmetic mean into SO(3), same as 'mean' Rs <- ruars(20, rcayley) Rbar <- colSums(Rs)/nrow(Rs) project.SO3(Rbar) #The following is equivalent mean(Rs)
