用matllab工具箱去实现绘图问题，可直接运行(To complete the huitu problem by matlab language)

powell code for matlab

matlab 云模型的源代码实现,是非常好的资料(It is based on the cloud caluate wih matlab computing)

该代码利用matlab，根据各类边界条件的设定，实现了FDTD的算法。( This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a three-dimensional Cartesian space lattice comprised of uniform cubic grid cells.)

matlab编程指导书，用于辅助matlab编程学习。(matlab programming instructions, for assisting matlab programming learning.)

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
