说明：  多焦点图像融合 利用基于双边梯度的锐化标准 相当对应的论文是J. Tian, L. Chen, L. Ma and W. Yu, "Multi-focus image fusion using a bilateral gradient-based sharpness criterion,"(This is a demo program of the paper J. Tian, L. Chen, L. Ma and W. Yu, "Multi-focus image fusion using a bilateral gradient-based sharpness criterion," Optics Communications, Vol. 284, Jan. 2011, pp. 80-87.)

说明：  matlab编写，贝叶斯估计程序，简单易懂。(Matlab prepared, Bayesian estimation procedures, simple and understandable.)

衰落信道仿真 function r = rayleigh( fd, fs, Ns ) r = rayleigh(fd,fs,N) A Rayleigh fading simulator based on Clarke s Model Creates a Rayleigh random process with PSD determined by the vehicle s speed. INPUTS: fd = doppler frequency set fd = v*cos(theta)/lambda v = velocity (meters per second) lambda = carrier wavelength (meters) theta = angle w/ respect to tangent (radians). fs = sample frequency (Samples per second) Ns = number of samples of the Rayleigh fading process to produce OUTPUTS: r = row vector containing Ns samples of the Rayleigh fading process Author: Matthew C. Valenti Mobile and Portable Radio Research Group Virginia Tech For Academic Use Only (Fading channel simulation)

针对医疗中的心电信号，利用奇异性检测的方法检测R波的位置,并给出模极大曲线(against the medical ECG, the use of the singular method of detection of R-wave detection of the location, and gives modulus maxima curve)

一个单位负反馈系统的根轨迹法超前校正。可直接在matlab中打开并运行。(A negative feedback system unit root locus method leading correction. Directly in matlab open and run.)

调试成功的测距定位仿真（TOA）。三个函数的作用分别是：在一个正方形区域内随机选择10个点；在这10个点中选择被测结点和参考结点；LSE位置计算。(Ranging and Location debug successful simulation (TOA). The role of the three functions are: a square area in 10 randomly selected points 10 points in the selected node under test and reference nodes LSE position calculation.)
