EnKF集合卡尔曼滤波代码，用于读写模式集合，包括两种扰动观测分析方案。(These files illustrate the model used for storing, reading and writing the ensemble of model states.)

利用楚列斯基分解法和平方根法分解对称矩阵，较为实用(use the Cholesky method and esquare-root method to solve the problem of Triangle decomposition of matrix)

说明：  fluent中udf的实例 计算曳力的例程 可以作为参考以及udf帮助手册(The example of UDF in fluent can be used as a reference to calculate the traction)

说明：  此程序为分段最小二乘算法曲线拟合,可对一模型进行分段拟合,增加准确性和精确度.(This program is sub-least-squares curve fitting algorithm can be fitted to a sub-model to increase the accuracy and precision.)

加入重复控制，模拟数据分析处理的过程，通过虚拟阵元进行DOA估计。( Join repetitive control, Analog data analysis processing, Conducted through virtual array DOA estimation.)

ransac直线拟合：使用ransac方法剔除不好的点，留下好的点做直线拟合，这样拟合出的直线更符合实际，因为没有了错误数据的参与。(ransac linear fitting: Use ransac methods eliminate the bad points, making a good point to make fitting a straight line, so that the fitted straight line is more realistic, because there is no involvement of erroneous data.)

重力勘探多次滑动平均方法。给出地址参数，建立网格模型，按网格进行滑动平均。得到平滑后的重力数据。可以去噪。(gravity window moving iteration)

说明：  将GNSS RINEX数据转换为电离层总电子含量(GTEX格式)(Convert GNSS RINEX data to Ionospheric Total Electron Content (GTEX format))
