matlab 实现ar模型中的burg 算法 ，源程序非调用 。可以直接使用(The matlab burg algorithm in ar model, source of non-call.)

处理nc文件，生成grads用的ctl文件和数据(deal with netcdf file,and output the ctl file and data for the Grads software！)

传统的宽带信号中抑制正弦干扰的方法是采用陷波器(notch filter),为此需要精确知道干扰正弦的频率.然而当干扰正弦频率是缓慢变化时,且选频率特性要求十分尖锐时,则最好采用自适应噪声抵消的方法.下图是用一个二阶FIR的LMS自适应滤波器消除正弦干扰的一个方案。该代码实现了以下功能： 1) 借助MATLAB画出了滤波器的误差性能曲面和误差性能曲面的等值曲线； 2） 给出了最陡下降法以及LMS算法的计算公式； 3） 用MATLAB产生了方差为0.05, 均值为0白噪音S(n)，并画出某次采样得到的波形； 4） 根据 2）中的公式，并利用 3）中产生的S(n)，在 1）中的误差性能曲面的等值曲线上叠加画出了采用最陡下降法以及LMS法时H(n)的在叠代过程中的轨迹曲线； 5）用MATLAB计算并画出了LMS法时误差随时间n的变化曲线（对应S(n)的某一次的一次实现）和e(n)波形； 6）在 1）中的误差性能曲面的等值曲线上，叠加画出采用LMS法得到的100次实验中的H(n)的平均值的轨迹曲线； 7）最终对结果进行了分析，具体见压缩包的word文档。 (Wideband signal in the conventional sinusoidal interference suppression method is the use notch filter (notch filter), this requires precise knowledge of the frequency of a sinusoidal interference .

IE自打印插件，在IE5中可以使用Webbrowser控件的ExecWB方法来实现自动无提示打印，但在>IE6版本此方法已经无效，此IE插件为此而产生。 此插件也是调用IE内置的打印功能，相当于window.external.Print() -> ExecWB(OLECMDID_PRINT,OLECMDEXECOPT_DONTPROMPTUSER,EmptyParam,EmptyParam) 仅此而已(IE print)

实现AM信号的输入以及相干解调前后的比较(The realization of the input AM signal, as well as compare before and after coherent demodulation)

Goal of the project was to implement numerical methods for solving systems of linear algebraic equations using MATLAB software. First of all I had to learn the structures of programming in MATLAB, later on I was able to implement and test numerical algorithms for solving given problems. All results, comments and conclusion are placed in this report. At the end of the report one can find my MATLAB programs, and sources which were used as a help for me during evaluation. Each task is presented under separated heading, with its full description, problem discussion, my approach for solving it and explanation.
