orthprocr R Documentation
Orthogonal Procrustes Analysis
Description
Simple function to rotate matrix X so that it matches the target matrix Z as
closely as possible, by minimizing ||Z - XQ|| where Z and X are of the same
size and Q is an orthogonal matrix. The algorithm is based on the singular
value decomposition (SVD) (see e.g. the reference).
Usage
orthprocr(Z, X)
Arguments
Z
The target matrix
X
The matrix to be rotated, which must be of the same size as Z.
Value
A list with the following 2 elements:
Q
The rotation matrix
XQ
The matrix X after rotation
