LU decomposition program.

说明：  SIRP法仿真K分布杂波，之前有下载过类似的，但是建立非线性表时的函数定义是有错误的，进行了修改，可以得到较好的估计效果(Simulating K distribution clutter by SIRP, similar to the code which been downloaded before, but when the establishment of non-linear function is wrong and modified, you can get a better estimate effect )

C#写的两个简单的小程序，分别用牛顿插值法和三次样条插值法来进行插值。(A program written by C#. It uses Newton Interpolation Method and Spline Interpolation Method )

多种曲线拟合方法，包括埃尔米特插值，差商，牛顿法，龙格库塔法( U591A u79CD u66F2 u7EBF u62DF u5408 u65B9 u6CD5 uFF0C u5305 u62EC u57C3 u5C14 u7C93 u7279 u63D2 u503C uFF0C u5DEE u5546 uFF0C u725B u987F u6CD5 uFF0C U9F99 u683C u5E93 u5854 u6CD5)

说明：  一个简单的matlab程序，用于实现自回归AR模型。( U4E00 u4E2A u7B80 u5355 u7684matlab u7A0B u5E8F uFF0C u7528 u4E8E u5B9E u73B0 u81EA u56DE u5F52AR u6A21 u578B u3002)

流体力学中有限体积法的求解程序，matlab代码-Finite volume method for solving procedures, matlab code(matlab code, -Finite, volume, method, for, solving, procedures, MATLAB, code)

说明：  分数阶傅里叶变换计算方面的文章，另附程序清单(Fractional Fourier transform calculation of the article, followed the list of procedures)

利用5阶WENO有限差分法求解一维Euler方程组，给出求解Sod型激波管问题的详细程序。(The use of 5-order WENO finite difference method for solving one-dimensional Euler equations given type of shock tube problem solving Sod detailed procedures.)

使用Matlab编程，对教材74页例3.3.1进行编程仿真。其中，正电压A的值、噪声方差值、每个码元周期内的采样点数N自行设定（可设置为可调的变量）。噪声值可使用Matlab中产生高斯随机数的函数来进行仿真。贝叶斯检测判决式中，先验概率P(H1)=P(H0)，判断错误的代价因子设为1，判断正确的代价因子设为0. 按照上述参数的设定进行仿真，实现对仿真数据的贝叶斯检测判决；循环生成仿真数据，并进行判决结果的统计，即记录判决正确的次数，估计正确判决的概率。(The use of Matlab programming, teaching materials 74 pages of 3.3.1 programming simulation. Among them, the value of positive voltage A, the variance of noise, the number of sampling points in each symbol cycle (N) can be set by itself (adjustable variable). Noise values can be simulated using the function of generating Gauss random numbers in Matlab. In the Bias detection decision, the prior probability P (H1) =P (H0), the factor of error judgment is set to 1, and the correct cost factor is set to 0. According to the simulation parameters and realize the judgment of Bayesian detection simulation data; generating cycle simulation data, statistics and decision, which records the correct number of judgment, the estimated probability of correct decision.)
