一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, the program uses 16QAM modulation, the source of a string of two binary modulation, with the Raised Cosine modulated baseband functions, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter demodulation, demodulation constellation plot using the minimum Euclidean distance decoding decision, bit error rate calculation.)

matlab实现信号波形插值运算，其中给出了包含sin函数和sinc函数的插值源代码(matlab signal waveform interpolation, which gives the source code contains the sin function and the sinc function interpolation)

这是用在MATLAB环境上，做出的火灾预警系统的论文，基于多传感器数据融合技术的加以改进的火灾预警系统。(It is used in the MATLAB environment, make a fire warning system papers, based on multi-sensor data to improve the fire warning system integration technology.)

实现人脸特征定位及人脸描述符提取功能。很好很强大。( To get started, run "demo". This detects faces in the example image, loading cached detections from files if available, localizes the facial features and extracts descriptors for each face.)

采用经典的阴性选择算法N-NSA，用IRIS数据集对算法进行耐受和检测，检测器半径固定不变，检测效率不高，因此需要采用变半径的方法检测(The negative selection algorithm using the classical N-NSA, with the IRIS data set of algorithms for tolerance and detection, the detector radius is fixed, detection efficiency is not high, requiring the use of variable radius method to detect)

MAKELATT Create lattice L = MAKELATT(KIND,PTS,DIM) makes desired kind of dim-dimensional finite lattice that consists of pts elements. Available designs are listed in the table below. All the generated lattices are geometrically uniform. The lattice points are chosen from the origin to higher shells. Sometimes its usefull to generate lattices from the number of one dimensional pattern side i.e. PTS = DIM ^ SIDE. Table of available designs Design | Dimension | KIND -----------+-----------+---------- Zn | n>=1 | Z An | n>=1 | A Dn | n>=3 | D Hexagonal | n=2 | Hex fcc | n=3 | fcc

蒙特卡洛模拟蒙特卡罗模拟因摩纳哥著名的赌场而得名。它能够帮助人们从数学上表述物理、化学、工程、经济学以及环境动力学中一些非常复杂的相互作用。 数学家们称这种表述为"模式"，而当一种模式足够精确时， 他能产生与实际操作中对同一条件相同的反应。但蒙特卡罗模拟有一个危险的缺陷: 如果必须输入一个模式中的随机数并不像设想的那样是随机数， 而却构成一些微妙的非随机模式， 那么整个的模拟(及其预测结果)都可能是错的。(Monte Carlo simulation)
