compute a closed curve through given points

Specify the number of your data points:
n =
Important: 4 <= n <= 100 !

Please specify your data points here (x(i),y(i)), i=1,n:
Important: each two successive points must be different
your input must have the form as follows
(1,0)(0,1)(-1,0)(0,-1)
and can extend over up to eleven lines.
(1,0)(0,1)(-1,0)(0,-1)

If you want to specify weights for the different distances
of successive points, click here:

Weights: w(i),i=1,n: Separate values w(i) by blank or comma. 1 2 1 2
