LONLAT2MINDIST - computes minimum distances in kms between points. Usage: [dist,indices] = lonlat2mindist( coords1, coords2, DIM ) coords1 and coords2 should have the lon, lat coordinates of the points you want the distance between. One of coords1 and coords2 should be a 2xM size matrix and the other should be a Nx2 size matrix. This function will then use lonlat2dist to compute the distance between all pairs of points. Then min will be used to find the point with the minimum distance along dimension DIM. If DIM is not given, then the short dimension of coords1 will be used. This function will have problems determining DIM automatically if coords1 is a 2x2 matrix. In that case, specify DIM explicitly and make the columns of coords1 longitude and latitude, respectively. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% $Id: lonlat2mindist.m,v 1.2 2004-09-08 03:31:13 dmk Exp $ Copyright (C) 2001 David M.
