matlab在数学建模中的一些有用例子,希望对大家有所帮助.(matlab in the mathematical modeling of some useful examples, and they hope to be helpful to everyone.)

Matlab programs for turbo equalization. Requires Matlab Version 7.

二维光子晶体禁带的遗传优化算法，在平面波展开法的基础上，使用遗传算法寻找具有最大光子禁带的二维光子晶体结构(Two-dimensional photonic crystal band gap genetic algorithm, in the plane wave expansion method based on the use of genetic algorithms to find a maximum two-dimensional photonic band structure of photonic crystals)

K-SVD是一种经典的字典训练算法，依据误差最小原则，对误差项进行SVD分解，选择使误差最小的分解项作为更新的字典原子和对应的原子系数，经过不断的迭代从而得到优化的解。(K-SVD is a classic dictionary training algorithm, based on the principle of minimum error, the error items SVD decomposition, choose to make the smallest error decomposition item as an updated dictionary of atoms and atomic corresponding coefficient, through constant iteration to obtain an optimized solution.)

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).)

WAVEVIB generates a vibroseis waveform (Clauder wavelet) by ％ first calling SWEEP to generate a linear sweep and then calling ％ AUTO to autocorrelate that sweep. Theoretically, the autocorrelation ％ length is ~ 2*slength but only only the central wlength long ％ part is generated. This is like windowing the auto with a boxcar.(WAVEVIB generates a vibroseis waveform (Clauder wavelet) by first calling SWEEP to generate a linear sweep and then calling AUTO to autocorrelate that sweep.
