We describe the graph of each $\lambda_k$ intuitively. For each $i \in I$, draw an isosceles triangle with base the interval $(b_i, d_i)$ on the horizontal $t$-axis, and sides with slope 1 and $-1$. This subdivides the plane into a number of polygonal regions. Label each of these regions by the number of triangles containing it. If $P_k$ is the union of the polygonal regions with values at least $k$, then the graph of $\lambda_k$ is the upper contour of $P_k$, with $\lambda_k(a) = 0$ if the vertical line $t=a$ does not intersect $P_k$. |

Rename distance_matrix kwarg to distance_matrices - Add checks for square input when distance_matrices is set to True - More comprehensive/friendly error messages and warnings * Increase generality of ripser function when metric == 'precomputed' Sklearn's pairwise_distances is no longer called when metric='precomputed'. This is because pairwise_distances checks for positivity and finite input in that case, but this is unnecessarily restrictive for ripser. pairwise_distances also checks for square input so this is no longer checked in the case metric='precomputed'. But the ripser function is not meant for use in isolation. It is meant to be called by a VietorisRipsPersistence instance, and input validation can be offloaded to that class. In particular, 9bab872 introduces checks for square input. * Add tests for check_point_clouds * Refresh docstrings for VietorisRipsPersistence - Mention "adjacency matrices of weighted undirected graphs" as well as distance matrices - Mention compatibility with filtration in docstrings for fit and transform * Add citing entry to README.rst and doc/faq.rst (#389) * Add citation section in README * Add citation info to FAQ page in docs Signed-off-by: Guillaume Tauzin <guillaumetauzin.ut@gmail.com> Co-authored-by: Umberto Lupo <46537483+ulupo@users.noreply.github.com> * Fix markdown subsection formatting (#390) * Fix citing giotto-tda section * Fix Important link section * Prepare release 0.2.1 (#391) * Make the docs and push to a test branch in gtda-docs * Fix indentation Co-authored-by: Umberto Lupo <46537483+ulupo@users.noreply.github.com> Co-authored-by: Guillaume Tauzin <guillaumetauzin.ut@gmail.com> Co-authored-by: Guillaume Tauzin <guillaume.tauzin@epfl.ch> Co-authored-by: Umberto <u.lupo@l2f.ch> Co-authored-by: Anibal M.
