This file tells how to do some common things you'll want to do with Iterate!
version 3.11.
How to quickly iterate a bunch of points to get an overview of what the
function looks like
══════════════════════════════════════════════════════════════════════════════
1. <A> to automatically enter points on the iteration stack.
2. <I> to iterate the points you've entered.
How to enter my own function
══════════════════════════════════════════════════════════════════════════════
Use <E> to edit a user function file. At first you'll want to choose an
existing function file (extension ".frm") and modify it.
You can also use the <F> command and choose Function U. This selects the User
Function, but doesn't allow you to edit it as the <E> command does.
How to explore Julia Sets
══════════════════════════════════════════════════════════════════════════════
1. Choose Function E using the <F> command. Enter the parameters you
want as 'a' and 'b'.
2. Draw the Julia Set using the <J> command.
3. Use the <H> command to hide the graphics help line (this makes the
<M> command work much better.
4. Move the cursor to various places in the Julia Set and use the <M>
command to trace the iterates and <Space> to draw the iterates.
How to enter Julia Set parameters directly from the Mandelbrot Set
══════════════════════════════════════════════════════════════════════════════
1. Use the <F> command and choose Function E.
2. Use the <R> command and load "Mandelbr.gph".
3. Move the cursor to any spot in or near the Mandelbrot Set.
4. Press <Z> to load these coordinates as the parameters.
5. Press <J> to draw the Julia Set associated with these parameters.
6. Use <Space> and <M> to investigate the properties of Function E with
these parameters.
You will see amazing correlations between the area of the Mandelbrot Set you
choose and the resulting Julia Set.
