Audio signal modelling containing a sequence of 2 identical chirp signals with an addition to filtering an image using simple low-pass 1-D filter.

利用巴特沃斯滤波器，实现数字信号的频谱分析 ，包括幅值谱，相位谱，群延时谱(Spectrum analysis of digital signal)

用bp神经网络对经提取得到的信号特征参数进行信号的模式识别。(Bp neural network used by the signal characteristic parameters were extracted for signal pattern recognition.)

遗传算法解决作业车间调度问题，这一M文件为遗传算子的交叉操作(Genetic algorithms to solve the job shop scheduling problem, the M-file for the genetic operators crossover operation)

这是matlab宝典里面的源代码 相信对于开发着有所帮助(This is a matlab source code inside the book and I believe that the development of a help)

用matlab编的 有什么错误请大家赐教 多多交流！！(Use of matlab for any errors, please enlighten us more exchanges! !)

说明：  在matlab环境下对图片进行压缩，使用算法为矩阵的奇异值分解(Matlab environment in the picture compression algorithm using singular value decomposition of the matrix)

进退法、0.618法、Powell法、罚函数法的程序设计, 用matlab编写，解优化问题(advancing and regressing method、0.618 method、Powell method、penalty function method, write in matlab, solve optimized problems.)

说明：  clc; clear all; close all; [filename, pathname, filterindex] = uigetfile({'*.jpg;*.tif;*.png;*.gif','All Image Files';... '*.*','All Files' }, '选择待处理图像', ... 'images\01.jpg'); file = fullfile(pathname, filename);%文件路径和文件名创建合成完整文件名 id = Get_Id(file);%得到file中的所有对象 Img = imread(file);%根据路径和文件名读取图片到Img [Plate, bw, Loc] = Pre_Process(Img); % 车牌区域预处理 result = Plate_Process(Plate, id); % 车牌区域二值化处理 % 寻找连续有文字的块，若长度大于某阈值，则认为该块有两个字符组成，需要分割 bw = Segmation(result); words = Main_Process(bw); % 主流程处理 Write_Mask(words, id); % 写出到模板库 str = Pattern_Recognition(words); % 识别(Mike is a student.
