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

program from calling VC++ programs from Matlab

说明：  matlab程序，可以完成图片格式=的转换(matlab program, you can complete the picture format = conversion)

Single phase active power filter

arduino用于控制ENCJ28芯片的库与文件( arduino ENCJ28 chip used to control and document library)

可用作数据的拟合和分类。核极限学习机采用了核函数，将数据投射到高维空间分类(It can be used for data fitting and classification. Kernel extreme learning machine uses kernel function to project data onto high-dimensional space.)

这是对波场做的一个TP变换，并进行反变换的程序。用matlab实现，可以实现波场分离的效果，文件中还自带了一个简易的理论地震记录(This is the wave field so a TP transform, and transform the process. Using Matlab to achieve, can achieve a separation of wave field effect, the paper also carried with them their own a simple theory of seismic records)
