su随机函数的生成，可用于数学和通信等过个领域，采用一般的生成方法(su random function generator that can be used such as math and communication areas, using the general method of generating)

正交镜像滤波器的设计，从正交镜像滤波器的远离出发设计,而且从结果中观察其相位和幅度。( Design a two-channel QMF filter bank The four filters in the filter bank are based on a lowpass prototype H(z) which is designed by this procedure. The analysis filters are HL(z) and HH(z) and the synthesis filters are GL(z) and GH(z), HL(z) = H(z) HH(z) = H(-z) GL(z) = 2 H(z) GH(z) =-2 H(-z)

This a simple demonstration of a content based image retri using 2 techniques. 1. Using knn for image retri 2. Using svm for image retri .

Project a vector b onto the column space of A.

fit_ML_rayleigh - Maximum Likelihood fit of the rayleigh distribution of i.i.d. samples!. Given the samples of a rayleigh distribution, the PDF parameter is found fits data to the probability of the form: p(r)=r*exp(-r^2/(2*s))/s with parameter: s format: result = fit_ML_rayleigh( x,hAx ) input: x - vector, samples with rayleigh distribution to be parameterized hAx - handle of an axis, on which the fitted distribution is plotted if h is given empty, a figure is created. output: result - structure with the fields s - fitted parameter CRB - Cram?r-Rao Bound for the estimator value RMS - RMS error of the estimation type- ML
