hough变换实现的图像中圆的检测，适用于计算机视觉初学者，简单容易理解(hough transform circle detection in images, Computer Vision for beginners, simple and easy to understand)

To find and estimate of the best solution and parameter in our problem we can use the evolutionary programming. PSO (particle swarm optimization) is an applicable method to catch this target. In these files I show the Simple PSO that it can be base of solve complicated problem, the code could run by MATLAB.

本源码给出了总体最小二乘方法的matlab实现，开发者可以了解最小二乘方法原理，以及程序实现。(This source gives the total least squares methods matlab realized, developers can understand the principle of least squares methods, and procedures to achieve.)

uploaded the polar codes for cooperative relay networks and the same can be used for compression

利用最小二乘法的原理高精度估计正弦波信号的幅值，频率和初相(The principle of using the least squares method estimated sine wave signal amplitude, frequency and initial phase of high-precision)

wiener滤波器的matlab程序，是自己编的，希望能对大家有用(wiener filter matlab program is own the hope that it can be useful for all of us)

This code calculate the steady seepage fo a concrete dam. The program is written in a manner that you can easily change the problem information. To understand how the program works, run main.m then follow the mentioned subroutines (.m files). There is enough comments in all .m files.

首先介绍MATLAB的基本知识及基本运算，使读者对MATLAB有一个概略的了解，然后系统论述图形绘制技术的基本概念、工作原理及在工程中的应用。书中精选科学和工程中常用的多个算法，全部采用MATLAB语言编程实现，并结合实例对算法程序进行验证和分析。其中详细讲解了MATLAB的基本知识、二维图形的绘制、三维图形的绘制、高级图形绘制技术、动画与视频、几何造型及GUI的程序设计等内容。(First introduced in MATLAB basic knowledge and basic operations, allowing the reader to have a rough understanding of MATLAB and then systematically discusses the basic concepts of graphics rendering technology, working principle and in engineering. The book featured commonly used in science and engineering multiple algorithms, all using MATLAB programming language, with examples for algorithm verification and analysis. Which explained in detail the basics of MATLAB, two-dimensional graphics rendering, 3D graphics rendering, advanced graphics rendering, animation and video, geometric modeling and GUI programming and other content.)

该算法描述了步进频率波探测生命体信号的方法，可以运行成功，非常不错(The algorithm describes a stepped-frequency signal wave detection method for a living body, you can run! ! !)

本程序用于电力系统计算的因子表形成、前代、回代，由matlab语言实现，希望有所帮助()
