Open-source licenses

eigen is built on the work of 145 open-source packages. Thank you to everyone who maintains them.

Ported and forked code

Some of eigen is adapted from other projects rather than installed as a package.

• ExcalidrawMIT

  eigen|vector> ports its elbow-arrow routing, freehand and elbow SVG path generation, and fractional-index repair

• fortune-sheetMIT

  the sheets engine and grid started as a fork of fortune-sheet 1.0.4

• LuckysheetMIT

  fortune-sheet's own origin; the conditional-format colour presets come from it

• fractional-indexingCC0-1.0

  vendored verbatim to pin z-order behaviour in eigen|vector>
