说明：  实现单自由度受迫振动，图像绘制,我们可以绘制出单自由的图像出来，供我们参考(we can use this specification for program to draw the picture,this program is writed by matlab and it is easy to understand.)

数值分析—全主元高斯消去法解线性方程组 (Numerical Analysis- Full-PCA Gaussian elimination method for solving linear equations)

MATLAB提供了各种曲线拟合方法，例如：Exponential, Fourier, Gaussing, Interpolant, Polynomial, Power, Rational, Smoothing Spline, Sum of Functions, Weibull等，当然，也可以使用 Custom Equations. cftool不仅可以绘制拟合后的曲线、给出拟合参数，还能给出拟合好坏的评价参数(Goodness of fit)如SSE, R-square, RMSE等数据，非常好用。但是如果我们已经确定了拟合的方法，只需要对数据进行计算，那么这种GUI的操作方式就不太适合了，比如在m文件中就不方便直接调用cftool。 (matlab has given a lot of method for curve combine ,we will give a new method and provide a matlab code.)

克里格法是地统计学的主要内容之一，从统计意义上说，是从变量相关性和变异性出发，在有限区域内对区域化变量的取值进行无偏、最优估计的一种方法；从插值角度讲是对空间分布的数据求线性最优、无偏内插估计一种方法。(Kriging method is one of the main contents of geostatistics. Statistically speaking, it is a method of unbiased and optimal estimation of regionalized variables in a limited area from the point of view of correlation and variation of variables; from the point of view of interpolation, it is a method of seeking linear optimum and unbiased interpolation estimation of spatial distribution data.
