M序列的产生代码，可生成工程上需要的标准M序列(M-sequence code generation)

用matlab仿真高斯分布；先产生高斯分布，并用matlab显示(Matlab simulation with Gaussian distribution first of Gaussian distribution, and display using matlab)

说明：  采用一种离散微分跟踪器的PID控制。被控对象是三阶传递函数，参考输入rin=20，干扰信号是0.5rands（1）。(PID Controller with Partial differential)

it is a rough code..i just copied from somewhere. it is in matlab and doing some thing

支持向量机和主成份分析的人脸检测代码，适合初学者。(Face detection code support vector machine and principal component analysis, suitable for beginners.)

对给定阵列给定周期的接受信号形成制定角度上的波束形成(For a given array to accept the formation of the development cycle of the signal given angle on the beamforming)

实现任意多个麦克风阵列的波束形成，麦克风阵列可以是加性的，也可以是差分的；阵列是均匀线阵，波束图经过线性归一化。(The microphone array can be additive or differential, and the array is uniform linear array, and the beam pattern is linearly normalized.)

交通规划 出行预测 底特律 matlab(traffic planing)

HOG（Histogram of Oriented Gradient）方向梯度直方图，主要用来提取图像特征，最常用的是结合svm进行行人检测。(HOG (Histogram of Oriented Gradient) direction of the gradient histogram is mainly used to extract image features, the most commonly used is a combination of svm detect pedestrians.)
