将发送滤波器和接受滤波器联合设计为无码间干扰的基带系统，而且具有最佳的抗加性高斯白噪声的性能。(Filter and receive filter will be sent free of joint design of the baseband inter-symbol interference in the system, and has the best resistance to the additive white Gaussian noise performance.)

此函数是根据柯西分布概率密度函数和累积分布函数的概念而编写的matlab程序，并附有一个测试程序。(This function is based on the Cauchy distribution probability density function and cumulative distribution function of the concept and write matlab program, together with a test program.)

功能描述：测试Levinson-Durbin算法 文件名：L_D_sim.m 测试用例： (1)x(n)+0.81*x(n-2)=u(n)，u(n)为高斯白噪声 (2)x(n)=u(n)+u(n-1)+u(n-2),u(n)为高斯白噪声 文件输出：两种测试用例情况下的功率谱 调用函数：function [A,E] = Levinson_Durbin_Algo(R,P) 被调用：无 作者：mingcheng 编写时间：2009-11-13 修改时间：2009-11-13 版本：V1.0 ( Function Description: Test Levinson-Durbin algorithm file name: L_D_sim.m test case: (1) x (n)+0.81* x (n-2) = u (n), u (n) is Gaussian white noise (2) x (n) = u (n)+ u (n-1)+ u (n-2), u (n) is Gaussian white noise file output: two tests use case in case of power spectrum call the function: function [A, E] = Levinson_Durbin_Algo (R, P) is called: No of: mingcheng write time :2009-11-13 modified :2009-11-13 version: V1.0 )

一个MATLAB模糊PID控制程序，弄成了TXT格式，代码是没变的，方便有些手机上查看(MATLAB CODE)

inmatrix函数创建一个与x矩阵同等大小的二、十进制换算对应表，所生成的换算对应表的第一行到末行依次对应二进制的高位到低位；并用此生成的换算对应表进行其他如求列和、列和代表的字符的运算；(inmatrix function creates a matrix of equal size with x 2, corresponding to decimal conversion table, the generated conversion table corresponding to the last line the first line of a high order corresponding to the low binary and use the resulting conversion table corresponding to the other, such as seeking out and , columns, and the representative character of the operation )

编写针对一个搜索点宏块比较的下面两个匹配函数：均方误差(MSE)、绝对值误差(MAD)。函数名直接使用简写。要求当前帧和参考帧的数据均采用二维数组表示。(Writing for a search point macroblock compare the following two matching functions: the mean square error (MSE), absolute error (MAD). The function name directly using shorthand. Requirements of the current frame and reference frame data are used two-dimensional array.)
