genproc: Generalized Procrustes Rotation

In lsbclust: Least-Squares Bilinear Clustering for Three-Way Data

Description

This function finds K orthogonal rotation matrices so that the rotated versions of the input configurations match each other optimally in the least-squares sense. The algorithm depends on the starting values for the rotation matrices. At present identity matrices are used as starting values. Only rotations / reflections are considered – no scaling or translation factors are included.

Usage

genproc(configs, maxit = 50L, reltol = 1e-06, random = FALSE)

Arguments

configs	A list of original configuration matrices
maxit	The maximum number of iterations allowed
reltol	The relative error tolerance for determining numeric convergence.
random	Logical indicating whether or not to use random starts (only applicable when the dimensionality is two).
