说明：  基于Reed_Solomon算法的DataMatrix条码纠错码的研究基于Reed_Solomon算法的DataMatrix条码纠错码的研究(DataMatrix bar code based on Reed_Solomon algorithm of error-correcting codes DataMatrix bar code based Reed_Solomon algorithm of error-correcting codes)

将MATLAB 函数 colfilt 用C语言编写， 在VS环境下(Use the programming language C to write the MATLAB function confilt )

M和m序列发生器，用于扩频通信中产生长度为2^N和2^N-1的伪随机码。同时还有产生bpsk调制的扩频调制和解调系统仿真，以及gold码的mat文件。(M and m sequence generator.Used for spread spectrum communication to generate the spread code.As well as bpsk spread spectrum system communication simulation.)

在命令窗口中输入lianxuwuran(t)，回车即可运行，其中t为时间，例如lianxuwuran(20)，表示经过20秒扩散的仿真图像。(Input lianxuwuran (t) in the command window, press Enter to run, where t is time, for example lianxuwuran (20), the proliferation after 20 seconds of simulated images.)

在通信系统仿真当中,常常会使用到伪随机信号,该源代码文件中包含两类最为常用的伪随机信号gold 序列的生成和m序列的生成,程序清晰有注解(In the communications system simulation are often used pseudo-random signal, the source code file contains two types of most commonly used pseudo-random signal sequence to generate gold and m sequences generated, the program has clear notes)

1.n个节点分段Lagrange插值多项式； 2.使用格式y=lagrange(x0,y0,x,k)； 3.输入项x0为n维插值节点向量，y0为n维被插函数值向量； 4.x为m维插值点向量，k为分段插值多项式次数，不超过3，缺省为k=1； 5.输出y为插值点x处的函数值；( 1.n a sub-node Lagrange interpolation polynomial 2. The use of the format y = lagrange (x0, y0, x, k) 3. Input x0 of interpolation nodes for the n-dimensional vector, y0 for n-dimensional vector function to be inserted 4.x interpolation points for the m-dimensional vector, k is the number of sub-polynomial interpolation, not more than 3, the default for k = 1 5. output y for the interpolation points x Department of function )

基于Microsoft Visual Basic的蒸汽养护计算机控制系统，并通过MATLAB仿真软件Simulink对模糊PID控制系统进行仿真。(Microsoft Visual Basic-based computer control system of steam curing, and simulation software MATLAB Simulink through the fuzzy PID control system simulation.)

HHT变换matlab程序 在matlab下运行即可，可以修改各种参数，采样点数，各种电能质量原始信号均由程序所得，可以信号叠加而来。比如电压跌落，谐波，暂时上升，中断等。 例子给出的是 电压暂降。(HHT transform matlab matlab program can be run in, you can modify various parameters, sampling points, a variety of power quality of the original signal by the program proceeds, may signal superimposed from. Such as voltage drop, harmonics, temporary rise interruption. The example given is voltage sags.)
