Rigid body transformations

Description

Applies a rigid body transformations to a landmark configuration or array

Usage

rigidbody(X,transx=0,transy=0,transz=0,thetax=0,thetay=0,thetaz=0)

Arguments

X	k x m matrix, or k x m x n array where k = number of landmarks and m = no of dimensions and n is no of specimens
transx	negative shift in x-coordinates
transy	negative shift in y-coordinates
transz	negative shift in z-coordinates
thetax	Rotation about x-axis in degrees
thetay	Rotation about y-axis in degrees
thetaz	Rotation about z-axis in degrees

Value

The transformed coordinates (X - trans) Rx Ry Rz
