Gaussin-Curve-Fitting-with-C

利用有限元法计算悬臂梁的实例，包含详细说明，适合用于课程设计。(Using the finite element method to calculate the cantilever instance, contains a detailed description, suitable for curriculum design.)

矩阵转换问题 行与列的个数均为n 的矩阵称为n 阶方阵。假定矩阵中的每个元素的值在0到9之间，则可以将矩阵中的所有元素按行依次排列得到一个“单行矩阵字符串”。(Matrix conversion, the number of rows and columns of the matrix n are called n-order square. Assume that each element of matrix value in the 0 to 9, you can press all the elements of the matrix rows in order of priority for a " single matrix string." )

以随机的中弱大气湍流为背景，可用于计算大气湍流下准直高斯光束的光强分布，光束扩展以及光束角漂移(The random weak atmospheric turbulence as the background can be used to calculate atmospheric turbulence of collimated Gaussian beam intensity distribution and beam propagation and beam angle drift)

含噪脉冲信号进行相关检测,信号处理中的旋转不变子空间法，代码里有很完整的注释和解释。( Noisy pulse correlation detection signal, Signal Processing ESPRIT method, Code, there are very complete notes and explanation.)

这是在MATLAB上的SIMULINK中实现的雷达系统仿真实例,用户可以自己设定目标距离,方向等参数,(This is an example of radar system simulation implemented in SIMULINK on MATLAB. The user can set the target distance, direction and other parameters by himself.)

复合材料破坏失效vumat子程序，使用hsshin准则判断失效，具有刚度缩减，(The VUMAT subroutine for failure of composite materials is judged by hsshin criterion, and stiffness is reduced.)

包括基本的克里金(Kriging)插值法实现代码，仅实现基本方法部分，不包含扩展克里金方法( 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 a simple 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 algorithms works best for relatively small numbers of observations (100-500). For larger numbers of observations I recommend the use of GSTAT. Note that kriging fails if there are two or more observa)

以重力异常为例，对重力异常曲线进行圆滑和求导数。(This is a matlab code.It about smooth and derivative algorithm.)

通过滑动T检验时间序列的变化趋势，一般多用于气象分析(T-test time series by sliding the trend, generally used for weather analysis)
