希尔伯特-黄变换源代码，每一步都很详细，对初学者有很大帮助(Hilbert- Huang Transform source code, each step is very detailed and very helpful for beginners)

常规PID控制器主要采用模拟PID控制器。这种控制器的控制规律是：根据给定值和输出值构成的偏差按比例、积分和微分通过线性组合构成控制量，对被控对象进行控制。(Conventional PID controller is used mainly analog PID controller. This controller is the control law: according to the given value and output value constitutes a deviation by proportional, integral and differential form by a linear combination of the amount of control, control of the controlled object.)

MATLAB7.0编程学习资料，编程必备学习资料，解决数学问题，英文文章，适合英文比较强的人使用(MATLAB7.0 programming learning materials, programming essential learning materials, and solving math problems, English articles, suitable for strong English)

MATLAB在物理中的应用，在学习物理的同时也能掌握一门计算机机技术，并能熟练应用计算机技术来学习物理与分析物理。 已通过测试。 (MATLAB in physics, to study physics at the same time able to grasp the technology of a computer machine and skilled application of computer technology to study physics and analysis of physics. Has been tested.)

指出了城市的主要污染物长期以来对城市居民造成了直接的危害，为更好地反映其污染变化趋势、加强污染防治工作和预防严重污染事件的发生，研究了污染预测方法，开展了污染预报工作。借助于MATLAB极强的非线性处理能力，来解决大气环境主要污染物自身复杂多变的问题，探讨了将MATLAB技术应用到空气污染的主份因子分析及预测领域中。(Pointed out that the city has long been the main pollutants of urban residents a direct harm, to better reflect its pollution trends, strengthen the prevention and control of pollution and prevention of serious pollution incidents, to study the pollution prediction method, carried out pollution forecast work. MATLAB help of strong nonlinear processing capabilities to solve complex atmospheric environment of major pollutants own issues discussed will be applied to the master copies of MATLAB technical factor analysis and forecasting in the field of air pollution.)
