CCL程式共享(标准非球面三阶衍射面位相曲线)

此程式用于显示三阶衍射面的位相曲线，编译链结后在指令行KEY入 DFPL N(N为衍射面别)
cmd dfpl(int sfn)
{
  float pi = 2*acos(0)&#59;
  float r = ap[sfn]&#59;
  float ri,w = wv[1]&#59;
  float pash, pash0 = 0, de1 , de2 , de3&#59;
  real size&#59;
  graphwin_open(1)&#59;
  for (size = .01&#59; size  .5&#59; size += 0.01)
  {
    /* Clear the window, draw the frame and refresh
     * the display:
    */
    GCLEAR&#59;
     pen 5&#59;
    viewport(.5-size, .5+size, .5-size, .5+size)&#59;
     frame&#59;
     gshow&#59;
    /* Let the frame remain visible for 1/10 second: */
     time_reset&#59;
    while (time  1) &#59;
    }
  pen 4&#59;
  gmv .5 .96&#59;
  lor 5&#59;
  lsz 2&#59;

  gmv 0 0.5&#59;
  glt 1 0.5&#59;
  stp outp off&#59;
  sbr&#59;
  spe sfn&#59;
  de1 = b4 , de2 = c4 , de3 = d4&#59;
  for (i = 0&#59; i1001&#59; i++)
   {
   ri = i*r/1000&#59;
   pash = fabs((2000*pi*(de1*ri**2 + de2*ri**4 + de3*ri**6)/w))&#59;
   if (pash0pash) pash0 = pash&#59;
   }
  gmv 0 0.5&#59;
  pen 3&#59;
  for (i = 0&#59; i1001&#59; i++)
   {
   ri = i*r/1000&#59;
   pash = (2000*pi*(de1*ri**2 + de2*ri**4 + de3*ri**6)/w)&#59;
   glt ri/r 0.5+pash/pash0/2&#59;
   
   }
   
   stp outp on&#59;  
   
}

怎么用？
