餐厅管理系统，可以增删改查，还在改进，还不行吗(Restaurant management system, you can add, delete, modify and check, is still improving, is not it possible?)

矩阵类加法的设计与实现 输入两个二维4*4的矩阵 实现这两个矩阵的加法-Matrix-type addition of the Design and Implementation of the importation of two two-dimensional matrix of 4* 4 matrix of the realization of these two adder

说明：  该程序用于计算直齿轮时变啮合刚度，其原理基于势能法。(The program is used to calculate the time-varying meshing stiffness of spur gears. Its principle is based on the potential energy method.)

说明：  基于STM32的HC-08蓝牙模块功能，已通过编译，可以直接下载运行。(The HC-08 Bluetooth module function based on STM32 has been compiled and can be downloaded and run directly.)
