matlab解线性方程组的源代码 function x=nagauss2(a,b,flag) ％ 用途：选列主元Gauss消去法解线性方程组ax=b ％ 格式：x=nagauss2(a,b,flag) a为系数矩阵，b为右端列向量，flag若为0，则显示中间过程 (Matlab solution of linear equations source code function nagauss2 x = (a , b, flag)% purposes : a selection PCA Gauss elimination method for solving linear equations ax = b% Format : nagauss2 x = (a, b, flag) for a coefficient matrix, b subguadratic column vector, if the flag is 0, then showed intermediate process)

使用matlab编写的各种类型的遗传算法，每一种都有注释说明 可以复制到M文件中运行(Matlab prepared using various types of genetic algorithms, each with explanatory notes can be copied to M to run in files)

说明：  wsn路由，用matlab仿真，具有选簇的功能(WSN routing, using matlab simulation, with the election of the functional cluster)

一维EM算法MATLAB实现，两分支高斯混合模型，均值和方差都不相同。(one dimensino EM algorithm implemented by MATLAB. Estimate the mean and variance of Gaussian Mixture Model with two branches.)

为对细管中的细胞作图像分析，所以就先作了一个管道区域分割的程序，用的的竖直直线和水平直线腐蚀的方法，比较基础和大家分享讨论^_^ 其中autothreshold是一个自动阈值分割的程序 (For the pairs of thin tube of cells for image analysis, so we made a first pipe region segmentation process, using the vertical and horizontal straight line method of corrosion, compare the basis and share the discussion ^ _ ^ One autothreshold is an automatic thresholding procedure )

收集了一些处理声音信号的实例，可供对音频处理的爱好者参考使用。(collected some examples of control noice signal. fans can used by reference. )

最小二乘法锂电池模拟，带遗忘因子的递推最小二乘法模拟。(The least squares method is used to simulate lithium battery and recursive least square method with forgetting factor.)

基于 MATLAB 的语音信号分析与处理的课程设计.录制一段自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用窗函数法或双线性变换设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的语音信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号(MATLAB-based voice signal analysis and processing of the curriculum. Record a voice signal itself, and the recorded signal is sampled draw sampled speech signal time-domain waveform and frequency spectrum filter performance given by using window method or the bilinear transformation to design a filter, and draw the filter frequency response then filter of their own design collection of the speech signal is filtered, the filtered signal to draw the time domain waveform and frequency spectrum, and filter the signal before and after comparison, analysis of signal changes playback voice signal)

Newton-Raphson算法是求解非线性方程组和有限元的主要程序，是工程人员的必会的算法(Newton-Raphson algorithm for solving nonlinear equations and the finite element of the main program, the engineering staff of the algorithm will)
