快速傅里叶变换 (FFT) 实现，给定信号x(t)=sin(2πf0t)，f0=50Hz，对x(t)以fs=200Hz进行抽样，抽样点数为N=16。编写程序实现对x(n)的快速傅里叶变换，求得相应的X(K)。(Fast Fourier Transform (FFT) to achieve a given signal x (t) = sin (2πf0t), f0 = 50Hz, for x (t) with fs = 200Hz sampling, the sampling points is N = 16. Procedures for the preparation of x (n) of the fast Fourier transform, obtained by the corresponding X (K).)

以优化SVM算法的参数c和g为例，对FA（萤火虫算法）MATLAB源码进行了逐行中文注解。(The firefly algorithm is based on the development of the bioluminescent biological characteristics of the natural world and is also based on the stochastic optimization algorithm of the population. There are two versions of the current literature on firefly algorithms. One is the Indian scholar Krishnanand and others, called GSO(glowworm swarm optimization); The other, proposed by the Cambridge scholar Xin-She Yang, is called the firefly algorithm. The bionic principle of the two algorithms is the same, but there are some differences in the implementation.)
