## Function Synopsis

    dist = m_xydist(x,y)

## Help text

     M_XYDIST Spherical earth distance between points in map projection coordinates.
       RANGE=M_XYDIST(X,Y) gives the distance in meters between
       successive points in the vectors X and Y which are coordinates
       in the current map projection. This function is useful for finding
       distances between points "picked off" a map, e.g.:

       Example:
       G = GINPUT(2); km_dist = M_XYDIST(G(:,1),G(:,2))/1000;

       See also M_LLDIST
