Fractional Fourier Transform

说明：  C++ SGP4 Satellite Library

说明：  集合卡尔曼滤波(EnKF) 数据同化方法可以避免了EKF 中协方差演变方程预报过程中出现的计算不准确和关于协方差矩阵的大量数据的存储问题,最主要的是可以有效的控制估计误差方差的增长,改善预报的效果。(Ensemble Kalman Filter (EnKF) data assimilation methods can be avoided in the EKF covariance forecasting the evolution equation arising in the course of the calculation is not accurate and on the covariance matrix of a large amount of data storage problems, the most important and effective control can be estimated error variance of the growth, improvement in forecasting results.)

三维PML-FDTD的C语言代码，完全匹配层的C语言实现(3D PML-FDTD in the C language code, perfectly matched layer in C language)

用matlab实现的二维两相水驱油数值模拟，可作为数值模拟课的作业。(Using matlab to achieve the two-dimensional two-phase water-flooding numerical simulation, numerical simulation can be used as homework assignment.)

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." )
