- Martin Map: uses the algorithm of Dr. Martin.
- ----------
- Change the values of a, b or c to get different patterns. The zoom option
- does not give more detail, but allows the size and position of the image to
- be changed. The routine is infinite, so you will need to select Stop to end
- the plot.
-
- Martin plots points, the colours of which are set from the main Plot Options
- dialogue box in the Effects menu. Choose Random plotting for best effects.
-
- From the menu you can select whether a, b or c are set randomly. Due to the
- way the algorithm works it is not possible to guess the size or position of
- the resulting image. New variables are not chosen when zooming.
-
- For each variable there is an associated maximum for the random number,
- which can be changed from the data panel.
-
- Algorithm:
- xx=py-sign(px)*sqrt(abs(b*px-c))
- py=a-px
- px=xx
- plotpoint(px,py)
- where px,py start off at 0.
