时频分布已被用来提供高分辨率表示大量的信号处理应用程序。然而,高分辨率和准确瞬时频率(如果)估计通常依赖于分布和使用信号相位函数的复杂性。(The time-frequency distribution has already been used to provide high resolution said a lot of signal processing applications. However, high resolution and accurate instantaneous frequency (if) estimates usually depends on the distribution and use of the complexity of the signal phase function.)

fit_rayleigh_pdf - Non Linear Least Squares fit of the Rayleigh distribution. given the samples of the histogram of the samples, finds the distribution parameter that fits the histogram samples.fits data to the probability of the form: p(r)=r*exp(-r^2/(2*s))/s with parameter: s format:result = fit_rayleigh_pdf( x,y,W,hAx ) input: y - vector, samples of the histogram to be fitted x - vector, position of the samples of the histogram (i.e. y = f(x,a)) W - matrix or scalar, a square weighting matrix of the size NxN where N = length(y), or 0 to indicate no weighting is needed. hAx - handle of an axis, on which the fitted distribution is plotted output: result - structure with the fields s - fitted parameter VAR - variance of the estimation type- weighted LS or not weighted LS iter- number of iteration for the solution

规划问题的matlab文件，规划问题在数学中的应用范围很广，值得一看(Matlab problem of planning documents, the planning problem at math in a very wide range of applications, worth a visit)

这是个统计模式识别工具箱，是各种统计模式识别算法用matlab语言的实现。(The Statistical Pattern Recognition Toolbox is a collection of pattern recognition (PR) methods implemented in Matlab.)
