e02zaf

Purpose

Synopsis

[point,ifail] = e02zaf(lamda,mu,x,y<,ifail>)

Description

 
 A set of m data points with rectangular Cartesian co-ordinates 
 x ,y  are sorted into panels defined by lines parallel to the y 
  r  r                                                          
 and x axes. The intercepts of these lines on the x and y axes are
 given in LAMDA(i), for i=5,6,...,PX-4 and MU(j), for 
 j=5,6,...,PY-4, respectively. The subroutine orders the data so 
 that all points in a panel occur before data in succeeding 
 panels, where the panels are numbered from bottom to top and then
 left to right, with the usual arrangement of axes. Within a panel 
 the points maintain their original order.
 
 A data point lying exactly on one or more panel sides is taken to
 be in the highest-numbered panel adjacent to the point. The 
 subroutine does not physically rearrange the data, but provides 
 the array POINT which contains a linked list for each panel, 
 pointing to the data in that panel.
