Class GaussianLatitudes

java.lang.Object

ucar.unidata.util.GaussianLatitudes

@Immutable
public class GaussianLatitudes
extends Object

Calculate Gaussian Latitudes by finding the roots of the ordinary Legendre polynomial of degree NLAT using Newton's iteration method. Moderately expensive to compute, so keep cache.
