用筛选法求m内的素数，给一个数求其是几位数，并输出每位数(Screening and m within a prime number, give a number for its several numbers, and the number of output per person. )

遗传算法Matlab源代码,优化目标函数比较广泛，是常用的算法之一，同时也是学习其他算法的基础。(Genetic algorithm (ga) )

使用低通滤波器从含有噪声的信号中提取有用的正弦波 (见实验指导书 实验九 数字滤波器中的第一题) 目的：用数字滤波器从含有高频噪声的采样数据中提取正弦信号。 要求：①输入信号为一正弦波，并加入一个白噪声的干扰来模拟信号传输中的随机干扰信号（用以模拟含有噪声采样序列）。 （模拟含有噪声采样序列具体可用正弦波信号叠加高频噪声来实现，为了使滤波效果明显，本实验的高频噪声是用高频均匀分布白噪声（Uniform）通过Butterworth高通滤波器过滤生成的，高通滤波器的截止频率设为10倍输入信号频率。） ②在程序中设计一个低通巴特沃斯滤波器，以滤除信号中的噪声分量，提取输入的正弦波信号 。 ③可调节信号滤波器的截止频率和阶数，可显示滤波前与滤波后的时域信号。 ④给出滤波前与滤波后的频谱特性的显示。 (Using low pass filter extracting useful sine wave signal containing noise(see experiment instruction digital filter in the first nine questions)Objective: to use digital filter sampling data extract containing high frequency noise sine signal.Requirements: (1) the input signal is a sine wave, and add a white noise interference to simulate the random disturbance signal of the signal transmission (to simulate contains noise sampling sequence).(simulated the sampling sequence contains noise available sine wave signal superposition of high frequency noise, in order to make the filtering effect is obvious, the experiment of high frequency noise is Uniform distribution with high frequency white noise (Uniform) by Butterworth high-pass filter to filter generated, high-pass filter cutoff frequency set to 10 times the size of the input signal frequency.)(2) in the program design a low-pass butterworth filter, in order to filter out the noise in the signal component, extract the input sine wav)

适用于初学者，能快速的理解掌握matlab的知识。偏向于matlab在自动控制中的代码的讲解(Applicable to beginners, can quickly understand and master the knowledge of matlab. In favor of MATLAB in the automatic control in the code. )

此压缩包包含两个程序，一个为录音程序，另一个为放音程序，皆用MATLAB编写，可以改变采集信号的频率和指定播放频率。是在学习数字信号处理中用到的一个小练习。欢迎尝试运行，和进一步修改。(This compressed package contains two programs, one for recording the program, and the other for playback program, are using MATLAB, you can change the frequency of collection and the specified playback signal frequency. Digital signal processing is used to learn a little practice. Welcome to try to run, and further modified.)
