I'd like to classify the data on coordinate.

Here are 2 example data.

data1 = [(1,1), (2,2), (3, 3), (4, 2), (5, 3), (6, 0)]

data2 = [(1,1), (2,2), (3, 10), (4, 9), (5, 10), (6, 0)]

The bold part have the same wave in above data.

The length are all different in my data set.

Is there any way that I can find the similar wave in many data like this?

Thank you.

Calcualte distance?

Distance = data2 - data1 = [(1,0), (2,0), (3, 7), (4, 7), (5, 7), (6, 0)]

And what will you treat as the same wave?

Any three (or more) nearby points that have the same distance...

  • $\begingroup$ Maybe we can calculate the distance of slope. $\endgroup$ – Jimmy Lin May 6 '15 at 2:09
