1d Persistent Homology compared with ripser.py

[xchhuang]

Hi all,

I ran an example here: https://persim.scikit-tda.org/notebooks/distances.html.

But I found that ripser.py is much faster on the same data and have much less points on the diagonal compared with this code. Is there any mismatch between them, or just because they filter the diagonal points ?
