一个简单的CZT chirp-Z变换例程(a simple example of CZT)

使用ABAQUS软件进行过渡网格划分，帮助用户建立良好的过渡网格的小工具(use the ABAQUS to divide the transition gridding)

该函数程序用于计算大气米散射中吸收、散射、衰减、后向散射。(Computation of Mie Efficiencies extinction (qext), scattering (qsca), absorption (qabs), backscattering (qb), asymmetry parameter (asy=<costeta>) and (qratio=qb/qsca).)

这个是计算声传播的各种模型 包括简正波kraken波数积分scooter等模型 有很好的学习价值 (a system program for acoustic propagation calculation)

说明：  利用python进行因子分析,因子分析可以进行降维!(Using Python factor analysis, factor analysis can reduce dimensionality!)

这是求解线性规划问题的revised simplex method的算法，需要得知原始的基和基本解(This is the revised simplex method for linear programming problem. It needs the initial basis and basic solution for input.)

说明：  九维的卡尔曼滤波跟踪算法，包括xyz三方向和各方向的位置，速度，加速度。(Nine-dimensional Kalman filter tracking algorithm, including the three xyz direction and the location of the direction, velocity, acceleration.)

python编写SM3密码杂凑算法,测试字符串abc, abcd*16(written in python SM3 password hash algorithm, the test string abc, abcd.* 16)

说明：  常用于分析降水、径流、气温等要素时间序列的趋势变化，其优点在于样本不需要遵循某一特定的分布，而且很少受到异常值的的干扰，计算简便。(It is often used to analyze the trend change of time series of factors such as precipitation, runoff and air temperature. Its advantage is that the sample does not need to follow a specific distribution, and is rarely disturbed by outliers, so it is easy to calculate.)

最小二乘支持向量机做预测。程序可运行学习。在matlab上运行。(This is a program about prediction using LSSVM.It can run successfully for learning.This program can be used on matlab.)
