a fresh eye looking at docstrings might be helpful |
I should be more familiar with how github works, but I'm not. Doesn't github render the rst files? I'm just seeing diff files. They seem okay, from what I saw, but it's it's a lot of code to read. |

<!-- ^^^^^ Please provide a concise, informative and self-explanatory title. Don't put issue numbers in there, do this in the PR body below. For example, instead of "Fixes #1234" use "Introduce new method to calculate 1+1" --> ### 📚 Description This PR adds constructions for all known skew Hadamard matrices of order up to 1000. The following changes have been made: - more skew Supplementary difference sets have been added - The functions for supplementary difference sets in `difference_family.py` have been changed so that now they also return the group to which the sets belong. This makes the functions consistent with the others contained in this file, and makes them more efficient. - Added construction of skew Hadamard matrices from complementary difference sets (and construction for complementary difference sets). - Added construction of skew Hadamard matrices from amicable Hadamard matrices and Orthogonal Designs (and construction for some amicable Hadamard matrices). Note that only commits from c0eb0c1 are new, the older ones where created in #35059. <!-- Describe your changes here in detail --> <!-- Why is this change required? What problem does it solve? --> <!-- If it resolves an open issue, please link to the issue here. For example "Closes #1337" --> ### 📝 Checklist <!-- Put an `x` in all the boxes that apply. --> <!-- If your change requires a documentation PR, please link it appropriately --> <!-- If you're unsure about any of these, don't hesitate to ask. We're here to help! --> - [x] I have made sure that the title is self-explanatory and the description concisely explains the PR. - [ ] I have linked an issue or discussion. - [x] I have created tests covering the changes. - [x] I have updated the documentation accordingly. ### ⌛ Dependencies <!-- List all open pull requests that this PR logically depends on --> <!-- - #xyz: short description why this is a dependency - #abc: ... --> #35059: this PR adds (non skew) Hadamard matrices of order <= 1000 URL: #35211 Reported by: MatteoCati Reviewer(s): Dima Pasechnik, MatteoCati, Travis Scrimshaw
