MATLAB编程经典程序 素数的判断，求0～100素数之和 源程序(The MATLAB programming classic program primes judgment, seeking 0 to 100 primes and source)

该m文件是数字信号处理实验课上的实验1：基本信号的产生(The m-file is an experimental course on digital signal processing experiment: basic signal generation)

一是利用计算机对正整数进行素因子分解认识素数，通过运用筛法与试除法寻找一定范围内的素数，体会到筛法比试除法有效但无法找出所有素数；二是通过若干特殊形式的素数的研究，寻找素数生成公式，发现一些结论；三是借助于非线性拟合技术，观察素数分布规律，利用其研究有关数论问题。(The first computer was used to prime factor decomposition of positive integers understanding of prime numbers, through the use of screening method and trial division to find prime numbers within a certain range, the division experienced a test of an effective screening method but can not identify all the prime numbers second is through a number of special form of prime numbers research, looking for prime number generation formula, found that some of the conclusions third, by means of non-linear fitting technique to observe the distribution of prime numbers, using their research on number theory problems.)

独立成分分析程序，实现独立成分分析的函数，可以再matlab中直接调用(Independent component analysis, independent component analysis functions directly call can matlab)

Output of Consettaltion when SNR=10,20

当信噪比较大时，采用广义最小二乘法可能会出现多个局部收敛点，解决这个问题的方法可用多级最小二乘法，一般来说多级最小二乘法包含三级辨识过程。利用输入输出数据，通过多级最小二乘法，可分别求的辅助模型，过程模型和噪声模型的参数估计值。在高噪声的情况下，多级最小二乘法明显优于广义最小二乘法，其收敛点唯一。(When the signal noise ratio (SNR), and by use of the generalized least squares method may appear more local convergence point, the way of solving this problem can be used multistage least squares method, and generally multistage least squares method includes three identification process. Using input/output data, through the multistage least squares, respectively for the auxiliary model, process model and noise model parameter estimation. In the high noise, multistage least squares method is obviously superior to the generalized least squares method, and its convergence point only.)

实现2ASK、2FSK、2PSK的调制与解调功能(2ASK, 2FSK, 2PSK modulation and demodulation functions)

pso 算法 这是网上下载的程序 借鉴一些阿(pso algorithm which is downloaded from some A procedure)

说明：  自己编写的萤火虫算法，可以用于聚类等多种用途。(I have written the firefly algorithm, can be used for clustering and other purposes.)
