灰色预测模型gm(1,1)适合初学者，只要数据就可以得到结果(Grey prediction model gm (1,1) for beginners)

说明：  利用分布傅里叶方法进行数值仿真，包含损耗、色散、SPM效应。 可以观察脉冲展宽与压缩，光孤子演化。(The distributed Fourier method is used for numerical simulation, including loss, dispersion and SPM effect. We can observe the pulse broadening and compression, and the evolution of optical solitons.)

PSO algorithm matlab code

加入3点或5点中值平滑处理后再绘制上述基频曲线与未平滑曲线比较，观测完整一段话音的基频包络变化情况(Add to 3:00 or 5:00 in the value of the smoothing then draw the base frequency curve is not a smooth curve compared with the observed period of complete voice baseband envelope changes)

Kalman工具箱,用做卡尔曼滤波的好工具！(Kalman toolbox,a good toolbox for carring out kalman filter.)

bridge rectifier simulation in matlab for the display how the harmonics are produced in ac system

该程序是一个振荡相位噪声模型。相位噪声是衡量频率标准源(高稳晶振、原子频标等)频稳质量的重要指标，随着频标源性能的不断改善，相应噪声量值越来越小，因而对相位噪声谱的测量要求也越来越高。(The program is a model of phase noise oscillator. Phase noise is a measure of frequency standard source (high stability crystal oscillator, atomic frequency standard, etc.) an important indicator of the quality of the frequency stability, with the frequency standard source performance continues to improve, the corresponding noise value smaller, and thus the phase noise spectrum of the measurement requirements higher and higher.)
