pc

Purpose This function calculates the pair correlation of points defined in [1].
Synopsis: R = pc(X, dr)
R = pc(X, dr, rm)
R = pc(X, dr, rm, str)
[R, r] = pc(X, ...)
Description: R = pc(X, dr) calculates the pair correlation for the point process X, type uint8, such that the spatial domain is divided into annular rings of radial width dr.

R = pc(X, dr, rm) calculates the pair correlation with annular rings of radius up to rm.

R = pc(X, dr, rm, str), when str='cluster', calculates the pair correlation with repect to parent points derived from the clusters of X.

[R, r] = pc(X, ...) returns the inner radius of all annular rings such that the pair correlation can be plotted as plot(r,R).
