线性拟合源代码，利用偏微分求导的方法进行多元的线性拟合(Linear fitting source code)

用matlab实现插值与拟合，统计领域用的比较多(Matlab implementation with interpolation and fitting, statistical areas are more used)

运用MATLAB软件编程，提取语音的基因频率(Voice of the gene frequency extraction)

说明：  仿生优化计算方法，可适用于基于选择类问题求解(Metaheuristic method, which can be used for problems based the requirement of sample selection)

说明：  这个是KPCA核主成分分析的代码，好用，里面也带有范例(This is the KPCA kernel principal component analysis code, which is easy to use and also contains examples.)

实现多输入的线性混合信号的分离,具体使用方法见readme.txt,readme.txt中的部分程序因某些原因，不能上传，请见谅(Realize multi-input linear mixed-signal separation, the specific use, see readme.txt, readme.txt some procedures for certain reasons, they should not upload, please forgive me)

演示龙格库塔方法的绝对稳定区域，从1阶到4阶，且阶数可以调整。另外，区域的左右边界可以计算出来(Absolutely stable region demonstrates Runge-Kutta methods, from an order to the fourth order, and the order can be adjusted. Further, around the boundary region can be calculated)

这是一个简单的FFT为无电位1 +1 +1 Ð 薛定谔方程的光束传播方法。如果该软件灵活，允许引入的术语（如果是极少数需要包括色散效应高阶导数）。例如，如果一个人渴望解决的一个方程的形式： （四/ dz的+ Ð ^ 2/dx ^ 2 - 0.25 * Ð ^ 3/dx ^ 3）== 0 Ÿ 它可以解决使用以下代码： Ž = linspace（0,1,512） x = linspace（-5,5,1024） psi0 =进出口（- x的。^ 2） Ð = D_lateral1D（十，2）-0.25 * D_lateral1D（十，3） 字段= LinearBPM（psi0，有D，Z） 凡D_lateral1D是一个函数，提供“取代”的微分算子。 这个函数是在一个非线性的BPM，我曾对（分步，谱方法等），将提交给我，当我完成他们的文件和组织功能更复杂的设置非常初期阶段。 (This is a simple FFT based beam propagation method for potential-free 1+1+1D Schrodinger equation. The software if flexible and allows to introduce high-order derivatives in the term (very handful if is needed to include dispersion effects). For example, if one desires to solve an equation in the form: (d/dz+ d^2/dx^2- 0.25*d^3/dx^3)Y == 0 It can be solved using the following code: z=linspace(0,1,512) x=linspace(-5,5,1024) psi0=exp(-x.^2) D=D_lateral1D(x,2)-0.25*D_lateral1D(x,3) field=LinearBPM(psi0,D,z) Where D_lateral1D is a provided function that "replaces" the derivative operator. This function is a very early stage in a more complex set of non-linear BPM functions that I have made (split-step, spectral methods, etc.) and I will submit them when I finish their documentation and organization. Sorry for my English, I m eager for your comments. )
