ADD TWO IMAGES WITHOUT FUNCTION

时间序列分析，采用了最小二乘（LS）与自回归(AR)的组合模型，并用MATLAB将其实现(Time series analysis, using a least-squares (LS) and autoregressive (AR) model combination and its implementation using MATLAB)

Test function : f= x+10*sin(x.*5)+7*cos(x.*4) Aim to get its max value( Test function: f = ' x+10* sin (x.* 5)+7* cos (x.* 4)' Aim to get its max value)

matlab fft()函数把所要求函数转换到频域(matlab fft () function required by the function switch to the frequency domain)

FDTD基本代码，计算电场和磁场时间更新(FDTD basic code, calculate the electric and magnetic time updates)

递推的最小二乘辨识程序，系统辨识中应用，用MATLAB实现，毕竟实用(Recursive least squares identification procedure, the application of system identification using MATLAB realize, after all, practical)

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

matlab仿真出刀刃的夫琅禾费衍射，其中有四副图，原图，二维衍射图样，函数图象和三维衍射图样(matlab simulation of the cutting edge of the Fraunhofer diffraction, which has four maps, original, two-dimensional diffraction patterns, functions, images and three-dimensional diffraction pattern)

微网仿真，根据IEEE14总线，可以直接运行。Matlab2016a使用(The simulation of microgrid can run directly according to the IEEE14 bus. Matlab2016a use)

cnv_encd.m　卷积编码程序 viterbi.m　　卷积译码程序 其它的是viterbi.m中用到的子函数(cnv_encd.m convolution coding procedures viterbi.m other convolution decoding process is used in viterbi.m Functions)
