基于二阶统计量的盲源分离算法例程

窗函数法设计有限冲激响应（FIR）滤波器，可根据工程上的设计指标来设计。(Window function design finite impulse response (FIR) filters, according to engineering design specifications to design.)

说明：  自己整理的各种matlab绘图代码，包括一维、二维、三维情况(Matlab drawing a variety of finishing their own code, including the one-dimensional, two-dimensional, three-dimensional case)

此方法可以实现流体力学中混沌的分叉分析，而且还可以分析皮卡尔曲面(this method can achieve hydrodynamics Chaos bifurcation analysis, but also surface can be analyzed Picard)

基于极坐标的牛顿拉夫逊潮流计算，MATLAB编程，只要把里面地址改成自己的地址就可以用了(Based on polar coordinates Newton Raphson power flow calculation, MATLAB programming, as long as the inside address into the address can be used)

Solving a 2D scattering problem using FEM

功能为特征提取，即它是从高维数据到低维数据(The source code for the feature selection to reduce the high-dimensional data low-dimensional data)

%负载 E_hat ；%Rt1499=reshape(e_hat(:,300),128,160) ；RT1499=imread("pic12.jpg") ；RT1499(find(abs(RT1499) > 0)) = 255 ；f=imread("pic13.jpg") ；GT1499=rgb2gray(f) ；[a,b,c]=size(RT1499) ；TP = 0 ；FP = 0 ；TN = 0 ；FN = 0 ；因为我 = 1：j 1:b =如果 GT1499(i,j) > 0 & RT1499(i,j) > 0TP = TP + 1 ；结束如果 GT1499(i,j) = = 0 和 RT1499(i,j) > 0FP = FP + 1 ；结束如果 GT1499(i,j) = = 0 和 RT1499 (i，j) = = 0TN = TN + 1 ；结束如果 GT1499(i,j) > 0 和 RT1499 (i，j) = = 0FN = FN + 1 ；结束结束结束DR=TP/(TP+FN) ；Precision=TP/(TP+FP) ；F_measure=2*DR*Precision/(DR+Precision) ；

基于MATLAB小波去噪程序，已经测试好了，可以直接使用的，提供给需要的朋友们(this is a study on wavelet)
