MATLAB实现信号的单边带调制 希尔伯特变换(MATLAB and the signal is single sideband modulation Hilbert transform)

本程序采用MATLAB语言对电力系统的各种短路计算进行分析计算，如单相接地短路，两相短路，两相接地短路等。(This procedure using MATLAB language for a variety of short-circuit calculation power system analysis and calculation, such as single-phase ground short circuit, two-phase short-circuit, two-phase ground short circuit.)

一堆数字信号处理的小程序,打个包发上来,上数字信号处理课写的,包括复倒谱、傅立叶变换、各种滤波器等~(heap of digital signal processing procedures for small, one packet onto fat, digital signal processing course was made, including the complex cepstrum, Fourier transform, various filter ~)

此为北京航空航天大学数值分析教材当中的2-5章所涉及问题的MATLAB源程序，程序附有详细的解释，值得学习。(This is the Beijing University of Aeronautics numerical analysis of materials in which the issues involved in Chapter 2-5 of the MATLAB source code, the program with a detailed explanation, it is worth learning.)

说明：  数值分析插值问题，还有用处啊 ！！！！大家可以好好学习一下。(Numerical Analysis of interpolation problems, but also the usefulness of ah! ! ! ! We can learn about.)

说明：  设计低通IIR滤波器；并将此低通滤波器映射为高通、带通或带阻滤波器。并验证变换后的滤波器是否满足指标。并求输入x(n)=[cos(w1n)+cos(w2n)]u(n)经过系统后的输出y(n)(Low-pass IIR filter design and mapping this low-pass filter high pass, band pass or band stop filter. And verify whether the filter transformation to meet the target. And to seek input x (n) = [cos (w1n)+ cos (w2n)] u (n) through the system output after the y (n))

In the field of artificial intelligence, a genetic algorithm (GA) is a search heuristic that mimics the process of natural selection. This heuristic (also sometimes called a metaheuristic) is routinely used to generate useful solutions to optimization and search problems.[1] Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems using techniques inspired by natural evolution, such as inheritance, mutation, selection, and crossover.
