跳频信号参数估计。参数为跳速、跳时和跳频频率集。文档包括一个短时傅里叶变换函数，一个参数估计函数，一个参数估计相对误差随SNR的曲线图和一个时频分析图。(Frequency hopping signal parameter estimation.Parameters for speed, to jump and jump frequency set.Document includes a function of the short-time Fourier transform, a parameter estimation function, a parameter to estimate relative error with the SNR curve and a time-frequency analysis diagram.)

此算法实现了对多径信号的估计及优化，仿真效果很好(muitipath option)

MATLAB基础练习，适合初学者，画正弦波形，证明公式，设计简单滤波器等(MATLAB based exercises, suitable for beginners, painting sine to prove the formula, simple design, filters, etc.)

opticalflow.m determines the velocity shift between two given images - ideally they should be virtually identical, but there is an affected translation between the two. imageshift.m creates a straightforward translation effect on an image - edges of the image wraps around to the other side
