一个关于随机风的simulink的仿真，大家看看(A random wind on simulink simulation, we look)

基于FFT的比值算法，是用比值法实现的MATLAB程序。 (Based on the ratio of FFT algorithm, is the ratio method using the MATLAB program realize.)

BP神经网络函数拟合源程序,可实现BP网络的算法拟合(BP neural network function fitting source, can be achieved BP network algorithm for fitting)

说明：  数值分析的部分matlab代码分享，如有错误还请见谅！(Part matlab code analysis of numerical analysis, please forgive me if there is any mistake.)

说明：  （拟合） 用给定的多项式，y=x3-6x2+5x-3，产生一组数据(xi,yi，i=1,2,…,n),再在yi上添加随机干扰(可用rand产生(0,1)均匀分布随机数,或用rands产生N(0,1)分布随机数)，然后用xi和添加了随机干扰的yi作的3次多项式拟合，与原系数比较。 如果作2或4次多项式拟合，结果如何？ ((Fitting) with a given polynomial, y = x3-6x2+5 x-3, generated a set of data (xi, yi, i = 1,2, ..., n), then add a random disturbance yi ( can be generated rand (0,1) uniformly distributed random number, or rands generated N (0,1) distribution of random numbers), and then added with xi and yi for random interference of the 3 times polynomial fitting, and the original coefficient. If 2 or 4 times for polynomial fitting, the result?)

改程序可以进行奇异值分解。是一种压缩后的奇异值分解。也可以进行广义奇异值分解。DSVD Damped SVD and GSVD regularization.(Program can change the singular value decomposition. Is a compressed singular value decomposition. Can also be generalized singular value decomposition. DSVD Damped SVD and GSVD regularization.)
