This method is a
Introduction to Matrix Algebra
ibgwww.colorado.eduTrace of a Matrix: The trace of a matrix is sometimes, although not always, denoted as tr(A). The trace is used only for square matrices and equals the sum of the diagonal elements of the matrix. For example, tr 3 7 2-1 6 4 9 0 -5 = 3+ 6 − 5 = 4 Orthogonal Matrices:
Least-Squares Rigid Motion Using SVD
igl.ethz.chremind the reader that the trace of a square matrix is the sum of the elements on the diagonal: tr(A) = P n i=1 a ii. See Figure 1 for an illustration of the algebraic manipulation. Therefore we are looking for a rotation Rthat maximizes tr WYTRX. Matrix trace has the property tr(AB) = tr(BA) (15) for any matrices A;Bof compatible dimensions ...
