Due to an increase in demand for and questions about direct disk access for Micrososft platforms, and due to the fact that Microsoft has no API for direct disk access, I am releasing this library much earlier than I intended at that start. I am still working on this code.

光伏电池模型，参考西南交大硕士研究生学位论文搭建(Photovoltaic cell model, the reference of Southwest Jiaotong University Graduate Thesis structures)

Description All the filters have needed neighbor data the current pixel in the image,here this function(res_window=cover_window(how many neighbor value for row ,how many neighbor value for column ,input image) produce the result( res_window(row,col,total size)) input inp_img=2d data(row * col) w=cover size w=[3 3] = 3x3 cover pixel generation output o_img=result 3d o_img(w(1),w(2),r*col) if inp_img=[1 2 3 4 5 6 ] w=[3 3] Soloution it will construct new image new_img=[0 0 0 0 0 0 1 2 3 0 0 4 5 6 0 0 0 0 0 0] result o_img(:,:,1)=[0 0 0 0 1 2 0 4 5] o_img(:,:,2)=[0 0 0 1 2 3 4 5 6] finally o_img(1:3,1:3,6) example a=imread( pears.png ) b=rgb2gray(a) c=cover_window( b,[3 3]) 3x3 window construction

粒子群算法 Matlab编程实现 这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。只有几十行代码。 (Particle swarm algorithm Matlab programming, this program is the basic particle swarm optimization algorithm procedures, using Matlab, very simple. Only a few dozen lines of code.)

基于MATLAB的异步电机svpwm仿真，有详细的3/2变换和park变换。(Asynchronous motor SVPWM simulation based on MATLAB has detailed 3/2 transform and park transformation.)

以高斯函数为载波的PPM调制解调，及于理想误码率曲线相比较的误码率曲线(Gaussian function of PPM modulation and demodulation of the carrier, and the desired BER curves compared to BER curves)

基于养老保险原理对养老保险抚养比进行测算，得出我国养老保险抚养比大小。(Based on the principle of old-age insurance pension dependency ratio is calculated on, come to the size of China' s pension dependency ratio.)

this program simulates 2D electromagnetic Maxwell equations , by using finite difference time domain method FDTD..and it simulates the perfect matched layer to prevent the reflections that may occure at the boundaries of the problem space

能对两个信号进行相关性分析，在进行分析时，注意不同的方法可能意义不太一样(Correlation analysis can be performed on the two signals)
