一种变步长的lms算法实现，用MATLAB编写。(A variable step size lms algorithm, using MATLAB write.)

SIGMA DELTA MODULATOR

constructive role of noise in signal detection from parallel arrays of quantizers.(A noisy input signal is observed by means of a parallel array of one-bit threshold quantizers,in which all the quantizer outputs are added to produce the array output.s(t)=s1(t)with prior probability P0,or s(t)=s0(t)with prior probability P1=1-P0 input signal-noise mixture x(t)=s(t)+n(t) x(t) is observed by means of a parallel array of M threshold comparators. yi(t)=U[x(t)+wi(t)-theta],i=1,2...M.wi(t) is threshold noise.Y(t)=y1(t)+y2(t)+...yM(t), the array output Y(t) is meansured at T distinct times.the plot is fthe theoretical value of minimal detection error probability Per varied with sigma.)

Deploy Nodes定位算法的matlab仿真编码(Deploy the Nodes positioning algorithm matlab simulation code)

一个新设计的OTSU算法，使用方法如下：％ load clown ％ subplot(221) ％ imshow(X/max(X(:))) ％ title( Original , FontWeight , bold ) ％ for n = 2:4 ％ Iseg = otsu(X,n) ％ subplot(2,2,n), colormap(gray) ％ imshow(Iseg) ％ title([ n = int2str(n)], FontWeight , bold ) ％ end(OTSU design a new algorithm, using the method as follows: load clown subplot (221) imshow (X/max (X (:))) title (Original, FontWeight, bold) for n = 2:4 Iseg = otsu (X, n) subplot (2,2, n), colormap (gray) imshow (Iseg) title ([n = int2str (n)], FontWeight, bold) end)

Demons registration算法的matlab源码(matlab sourse code for Demons Registration)

说明：  MATLAB求解最大lyapunov指数源代码(MATLAB to solve the largest index of the source code lyapunov)

说明：  是《信号与系统》第一章信号运算的实验内容，有详细的代码和实验原理(Is the &quot Signals and Systems&quot Chapter signal computing experiment content, code and test a detailed theory)

经典的疾病传播模型，包括SI、SIS、SIR模型等等(The classic model of disease transmission, including SI, SIR models, etc.)

说明：  本人经过对最小二乘法拟合程序进行了归纳汇总编写了这个MATLAB小程序，一般情况都适用。(General least squares fitting procedure code)
