二维经验模式分解代码，十分实用，希望对有需要的朋友有用(Two-dimensional empirical mode decomposition code, are very useful, want to be useful to have a friend in need)

说明：  经典ESPRIT算法，在等间距接受阵列的条件下，直接估计出我们想要接收信号的角度。八个接收天线，二个目标信号，噪声为高斯噪声。(Classical ESPRIT algorithm, such as spacing in the array to accept the conditions, we want to directly estimate the received signal point of view. Eight receiving antennas, two target signal and noise as Gaussian noise.)

说明：  Buck基础电路MATLAB的Simulink仿真，12V-5V，参数已经调好 PID控制Buck电路原理图（VISIO图）(Simulink simulation of Buck basic circuit MATLAB, 12V-5V, parameters have been adjusted PID control Buck circuit schematic (VISIO diagram))

分别利用fisher判别法和近邻法对一组声呐数据进行模式识别，计算分类的正确率(Respectively, and the use of fisher discriminant method nearest neighbor method sonar data to a set of pattern recognition, to calculate the correct classification rate)

分水岭测试算法，供参考，里面还有一些其他代码，共学习(Watershed test algorithm, for reference)

自己编写的ga（遗传算法）matlab工具箱。对比过，速度挺快的。(I have written ga (genetic algorithm) matlab toolbox. Been compared, the speed very fast.)

这是雷达幅度符合韦布尔分布的杂波仿真程序，功率谱为高斯谱，时域上分为I、Q两路。(This is consistent with the Weibull distribution range radar clutter simulation program, power spectrum for the Gaussian spectrum, the time domain is divided into I, Q two.)
