代码说明:

  通过设计一个二阶加权系数自适应横向FIR滤波器,对一个加随机噪声的正弦信号实现滤波。 具体设计方案为: 1,生成标准正弦信号S 2,生成等长的随机信号N 3,生成加随机噪声的正弦信号X 4,X通过参数可调数字滤波器,输出Y 5,Y与参考信号作差得到误差E 6,E通过自适应算法调整权值W 7,用LMS算法处理噪声干扰的信号,最终实现滤波器功能(A two order weighted coefficient adaptive transverse FIR filter is designed to filter a sinusoidal signal with random noise. The specific design scheme is as follows: 1, generating a standard sinusoidal signal S 2, generating an equal length random signal N 3, generating a sinusoidal signal X with random noise 4, X can adjust the digital filter by parameter and output Y 5, the difference between the Y and the reference signal is E 6, E adjusts the weight W through the adaptive algorithm 7, the LMS algorithm is used to deal with the noise interference signal, and the filter function is finally realized.)

    克里金法假定采样点之间的距离或方向可以反映可用于说明表面变化的空间相关性。克里金法工 具可将数学函数与指定数量的点或指定半径内的所有点进行拟合以确定每个位置的输出值。克里金法是一个多步过程;它包括数据的探索性统计分析、变异函数建模 和创建表面,还包括研究方差表面。当您了解数据中存在空间相关距离或方向偏差后,便会认为克里金法是最适合的方法。该方法通常用在土壤科学和地质中。(This function completes what I have started with the functions variogram and variogramfit. It is not intended to be a highly optimized code for performing kriging but may have educational value. Note that for using kriging, you should download the latest version of variogramfit. kriging uses ordinary kriging to interpolate a variable z measured at locations with the coordinates x and y at unsampled locations xi, yi. The function requires the variable vstruct that contains all necessary information on the variogram. vstruct is the forth output argument of the function variogramfit. This is a rudimentary, but easy to use function to perform an ordinary kriging interpolation. I call it rudimentary since it always includes ALL observations to estimate values at unsampled locations. This may not be necessary when sample locations are not within the autocorrelation range but would require something like a k nearest neighbor search algorithm or something similar. Thus, the alg)

  • newton_raphson
    Newton-Raphson算法 介绍 在科学计算和财经工程领域,许多数值算法都是通用的(至少在理论上是),可广泛地用于解决一类问题。一个大家熟悉的例子就是Newton-Raphson例程,它可用来寻找方程 f(x)=0的数值解。标准的数学表达式f(x)表示f是变量x的函数,其通常的表达形式为f(x,a,b,...)=0,f被定义为多于一个变量的函数。在这种情况下,Newton-Raphson算法试图把x以外的变量固定并作为参数,而寻找关于变量x的数值解。 由于Newton-Raphson算法需要知道被求解函数的确切表达,其传统实现方法是直接将代码嵌入到客户应用程序中。这就使得算法的实现代码经过针对不同被求解函数的少量修改后在客户程序中反复出现。 同许多其它数学例程一样,Newton-Raphson算法的具体实现是应该与特定用户无关的。并且,重复编码在任何情况下都应该尽量避免。我们很自然地会想到把该类例程作为库函数来实现,以使客户程序可以直接调用它们。但是,这种实现方式必然会涉及到如何将用户自定义函数(Newton-Raphson 例程需要调用该函数)封装成可以作为参数传递的形式。 (err)
