- NewtonBasin
- -----------
- This function calculates the n-th root of -1 ie. z^n-1=0, using the
- Newton-Raphson method. Floating point arithmetic is required so don't expect
- it to zip along. This function plots the colour based on the root we are
- converging to. Contrast this with NewtonIters which uses the iteration count.
-
- There are 2 data variables:
-
- Max Iter : iteration limit.
-
- e : The accuracy check value. The iteration is stopped when a root is found
- that solves the equation to within the 'e' accuracy value. Higher values of
- 'e' force greater accuracy and more iterations to be used, useful when
- zooming in.
-
- A 3d version can be drawn directly by turning on the 3d X/Y Plot option.
- See the 3d section of !MainHelp for details.

- Thanks to Joyce Haslam for providing this function.
