Monte Carlo方法课件，清华大学用的。 这是一份很好的Monte Carlo方法教程，详细的介绍了蒙特卡洛算法的知识和应用。-Monte Carlo method courseware, Tsinghua University. This is a very good tutorial Monte Carlo method.

我自己写的一个三次样条插值算法，自已感觉很严密，请大家指正。-I wrote it myself a cubic spline interpolation algorithm, self-feelings are very close, please correct me.

混响作为浅海自导系统特有的干扰，对水声信号检测性能的影响日趋凸显，而对混响抑制一直是水声信号处理研究中的热点和难点。对于浅海混响下主动自导系统来讲，混响主要来自海底和海面，资料中关于怎样建立浅海混响模型，在点射模型的基础上研究建立浅海混响谱模型和海面分形模型。

该程序是基于matlab平台的粒子群算法的实现程序，用来实现粒子群算法，程序简单易理解，对学习该方面知识的学者提供一定的帮助。

用fortran编写的复合形法的源程序，供大家参考。-fortran prepared with the complex method of the source, for your reference.

应用背景This application is to focus on the numerical methods in Computational Fluid Mechanics, dealing with aeronautics, hydraulics, heat and mass transfer etc. We konw fluids have the ability to transport matter and its propertities as well as transmit force, therefore fluid mechanics is a subject that is particularly open to cross fertilization with other sciences and disciplines of engineering. The subject of fluid mechanics will be highly relevant in domains such as chemical,metallurgical, biological and ecological engineering.关键技术 SIMPLE (Semi-Implicit Method for Pressure Linked Equations) algrithm is the principal numerical method to numerical simulate incompressible fluid flow, it can remove the difficults of fake pressure disturbance and neglecting specific pressure equation for incompressible fluid flow successful. The main thoughts and steps of SIMPLE algorithm are given in this application. The single-phase loc
