DoFun 3.0: Functional equations in mathematica

We present version 3.0 of the Mathematica package DoFun for the derivation of functional equations. In this version, the derivation of equations for correlation functions of composite operators was added. In the update, the general workflow was slightly modified taking into account experience with the previous version. In addition, various tools were included to improve the usage experience and the code was partially restructured for easier maintenance.

本报告推介了 Mathematica 软件包 DoFun 的第三个版本，该软件包旨在推导函数方程。在本版中，新增了对复合算子相关函数方程的推导功能。在此次更新中，考虑到先前版本的使用经验，对整体工作流程进行了细微调整。此外，为提升使用体验，纳入了多种辅助工具，并对代码结构进行了局部重构，以利维护。
