FDTD_2D_TM

说明：  使用matlab语言编写的由彩色图像到轮廓提取(Matlab language used by the color image to the contour extraction)

本程序实现随机数的产生和在相同调制方式下功率谱比较(the program of random number generation and modulation in the same way under the power spectral comparison)

robust control matlab program

机器学习中的垃圾邮件分类程序，用matlab做的。从以下链接下载垃圾邮件数据（spam data）：(数据已下载，放在spambase.zip) http://www-stat.stanford.edu/~tibs/ElemStatLearn/index.html 该数据包含57个邮件信息相关的变量，每条邮件可以被分类为垃圾邮件（Y=1）和非垃圾邮件（Y=0）。输出Y的值在文件中每一列的末尾。练习的目标是要预测电子邮件是否为垃圾邮件。 (Machine Learning spam classification procedures, using matlab to do. Data (spam data) from the following link to download the junk mail: (data has been downloaded, put spambase.zip) http://www-stat.stanford.edu/ ~ tibs/ElemStatLearn/index.html The data includes 57 e-mail messages related variables, each message can be classified as spam (Y = 1) and non-spam (Y = 0). Y value of the output end of each column in the file. The goal is to predict exercise email is spam.)

股票时间序列拟合算法，包括简单移动平均，加权移动平均等利用matlab实现(Stock time series fitting algorithms, including simple moving average, weighted moving average and so the use of matlab to achieve)

边界延拓镜像法和边界延拓自适应波形匹配法(Boundary extension by mirror and adaptive wave matching)

电能质量扰动信号信号通过hilbert变换得到瞬时频率，瞬时幅值，hilbert谱，边际谱等重要特征，从而实现特征提取。(Power quality disturbance signals are obtained by hilbert transform to obtain instantaneous frequency, instantaneous amplitude, hilbert spectrum, marginal spectrum and other important features, in order to achieve feature extraction.)

说明：  利用matlab编写的kalman滤波源程序，经过详细测试绝对可以可靠使用(prepared by the use of Matlab Kalman filtering source, after careful testing can absolutely reliable use! !)

说明：  用matlab调制解调2fsk信号,以及相应的作图方法(2fsk signal modulation and demodulation using matlab, and the corresponding mapping method)

it is matlab code and is for systems and signals by porakis that is very good for all
