说明：  STM32F103 蓝牙HC-05通讯程序亲测可用(STM32F103 Bluetooth HC-05 communication program is available for personal testing)

说明：  以悬臂梁为例，用有限元法编程生成质量矩阵和刚度矩阵（采用平面梁单元，单元数在10到30之间）。 使用matlab的用于广义特征值问题分析的函数（eig(A,B,'chol')，该命令使用乔莱斯基分解的方法，计算对称矩阵A和对称正定矩阵B的广义特征值问题。A对应刚度矩阵，B对应质量矩阵）计算梁的前三阶固有频率和振型，计算得到梁的前三阶固有频率和振型，并画出振型图。(Taking cantilever beam as an example, the mass matrix and stiffness matrix are programmed by finite element method (using planar beam elements, with units ranging from 10 to 30). Using Matlab's function (eig (A, B,'chol') for the generalized eigenvalue problem analysis, the command uses the Jo Lessky decomposition method to calculate the generalized eigenvalue problem of the symmetric matrix A and the symmetric positive definite matrix B. A corresponds to the stiffness matrix and B corresponding to the mass matrix. The first three natural frequencies and modes of the beam are calculated, and the first three natural frequencies and modes of the beams are calculated, and the vibration pattern is drawn.)

用S-Function写的ADRC仿真工程实例(The engineering example of the ADRC simulation with S-Function.)

大规模单目标协同进化优化算法，首先将大规模问题分解子问题，然后子问题分别求解，论文在压缩包内(The large scale problem is first decomposed into sub-problems and then solved separately)

语言之间跨平台的接口调用，非常有用，规避单语言功能(Cross platform interface calls between languages are very useful to avoid single language functions)
