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

说明：  雅克比迭代法求解方程组;雅克比迭代法就是众多迭代法中比较早且较简单的一种，其命名也是为纪念普鲁士著名数学家雅可比。雅克比迭代法的计算公式简单，每迭代一次只需计算一次矩阵和向量的乘法，且计算过程中原始矩阵A始终不变，比较容易并行计算。(Jacobian iterative method for solving equations Jacobi iteration is one of the earlier and simpler iteration methods, and its name is also in memory of Jacobi, a famous mathematician in Prussia. Jacobian iterative method has a simple calculation formula, each iteration only needs to calculate matrix and vector multiplication once, and the original matrix A is always the same in the calculation process, so it is easy to parallel calculation.)

Morphology, broadly, is the study of form or structure. Folkloristic morphology, then, is the study of the structure of folklore and fairy tales. Folkloristic morphology owes its existence to two seminal researchers and theorists: Russian scholar Vladimir Propp and Finnish folklorist Antti Aarne.
