计算长周期光纤光栅的纤芯基膜的有效折射率的程序，很基本(Calculation of long period fiber grating effective refractive index of core-based film program, very basic)

sparse representation

方程求根的matlab程序，用的是平行法则，仅供参考(Roots of the equation matlab program, using a parallel rule, for reference only)

基于模糊自动控制的分形滤波算法。通过计算分形维数选定滤波器实现自适应滤波去噪。(Automatic control based on fuzzy fractal filtering algorithm. By calculating the fractal dimension ， select adaptive filter to achieve de-noising .)

this is some basic matlab programs.

matlab code for maximum ratio combining, best code ever and the simplest one

共轭梯度算法，改进后的算法，比较好用，已经验证过了。(Conjugate gradient algorithm, the improved algorithm, more useful, has been verified.)

f=zeros(30,30) f(5:24,13:17)=1 imshow(f, notruesize ) F=fft2(f,256,256) F2=fftshift(F) figure,imshow(log(abs(F2)),[-1 5], notruesize )

主要是对测井资料进行分析，要对数据数字化之后进行，而且采样间隔一定(log Processing)

knn是一种分类算法，它是基于matlab的一种模式识别的经典算法，一般适用于样本个数较小的样本分类。(KNN, it is classification algorithm based on matlab a pattern recognition of the classic algorithm, generally applied in sample number of smaller sample classification. )
