| riemdist {shapes} | R Documentation |
Calculates the Riemannian shape distance $rho$ between two configurations
riemdist(x, y)
x |
k x m matrix (or complex k-vector for 2D data) where k = number of landmarks and m = no of dimensions |
y |
k x m matrix (or complex k-vector for 2D data) |
The Riemannian shape distance rho between the two configurations. Note 0 <= rho <= pi/2
