Worked on improving the documentation quality for the scipy/scipy repository by updating B-spline source references. Focused on replacing outdated material with newer UiO course notes and archiving inaccessible links to reduce link rot and enhance long-term usability. Emphasized documentation best practices and reference management, ensuring that users implementing B-splines have access to clearer, more reliable sourcing. Utilized Python and applied knowledge of data interpolation and spline theory to maintain technical accuracy. All changes were captured in a single, version-controlled commit, supporting reproducibility and maintainability. No bugs were fixed during this period, as the primary effort centered on documentation improvements.
