【matlab编程代做】基于k-means算法 可以作为参考使用学习([Do] matlab program generation based on k-means algorithm can be used as a reference study)

fft and dft is done withought functions..

说明：  matlab向dsp传递.dat文件的方法，很经典。(dsp matlab to pass. dat file method, it is classic.)

利用matlab离线处理数据实现经验模式分解（EMD）算法(Offline data processing using matlab to achieve empirical mode decomposition (EMD) algorithm)

The study documents the famous 3D engine for 3D developers learn to use.

杨氏双缝干涉 两相干光源到接收屏上P点距离r1=(D2+(y-a/2)2)1/2, r2=(D2+(y+a/2)2)1/2, 满足相干条件的光波叠加后，对于观察屏上某一确定点，即r1、r2确定后，叠加后的光强为 式中λ为光波的波长， 、 ，令相位差φ=2π（r2-r1）/λ, 最后可得公式如下： ， 最后光强I=4I0cos2（Φ/2）。 观察相干光叠加后光强的分布. (Young' s double slit interference two coherent light source to the point P on the receiving screen distance r1 = (D2+ (YA/2) 2) 1/2, r2 = (D2+ (y+a/2) 2) 1/2, meet coherent conditions lightwave after superposition, for a determined point on the viewing screen, i.e. R1, R2 is determined, the superimposed light intensity where λ is the wavelength of light, make the phase difference φ = 2π (R2-R1)/λ, final can be obtained using the following formula: Finally, the light intensity I = 4I0cos2 (φ/2). Observed coherent superposition of light intensity distribution.)
