Maple procedures for partial and functional derivatives

Abstract A package with new Maple V commands for the evaluation of partial derivatives, functional derivatives and integrals containing the Dirac delta function is presented. Some examples of the use of these commands in physics are shown. Title of program: partials Catalogue Id: ACTN_v1_0 Nature of problem Calculation of partial and functional derivatives of algebraic expressions. Versions of this program held in the CPC repository in Mendeley Data ACTN_v1_0; partials; 10.1016/0010-4655(94)90185-6 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)摘要 本研究提出一款包含全新Maple V命令的程序包，可用于计算含狄拉克δ函数（Dirac delta function）的偏导数、泛函导数与积分。同时展示了该系列命令在物理学领域的若干应用示例。 程序名称：partials 目录编号：ACTN_v1_0 问题性质 用于代数表达式的偏导数与泛函导数计算。 存放在Mendeley数据中的CPC知识库的该程序版本信息为： ACTN_v1_0; partials; 10.1016/0010-4655(94)90185-6 本程序源自贝尔法斯特女王大学维护的CPC程序库（1969-2019）
