mandelbrot_test():
  MATLAB/Octave version 6.4.0
  Test mandelbrot().


mandelbrot():
  Create an image of the Mandelbrot set.

  For each point C = X + i*Y
  with X range [-1.000000,-0.600000]
  and  Y range [0.000000,0.400000]
  carry out 21 iterations of the map
  Z(n+1) = Z(n)^2 + C.
  If the iterates stay bounded
  then C is a member of the Mandelbrot set.

  An image of the set is created using
    M = 101 pixels in the X direction and
    N = 101 pixels in the Y direction.
    COUNT_MAX = 21 = number of iterations.
