该库提供了用于表示几何表达式的表达树，并对这些表达式进行自动微分。这使得能够在位置级别写下几何表达式，并自动高效地计算雅可比矩阵和高阶导数而不损失精度。该库建立在 KDL 库之上，并使用相同的几何基元。KDL 基本基元的大多数运算符和函数在表达树库中都有对应的等效项

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.

Pushes, PRs, issues, reviews and comments — stars and forks excluded, so this is contribution rather than popularity

No issue or PR events — this repo's activity is pushes only.
Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 4 stars here means stars gained during the window, not the repo's star count.
