X-Ray function algorithm:
Reconstructs an approximation to a regular polygon or an ellipse from a finite number of noisy
x-ray measurements of the shape. See the section on Algorithms for more information.

Choose to reconstruct a regular polygon or an ellipse:  

A translation can be applied to the shape by entering a vector into the shift box
in the form "x; y".

You can enter mathematical expressions into the shift box
using the operators -, +, *, /, and ^. Please separate each operator
and operand by a space.
