一个计算器，实现加减乘除等，适合初学者学习，代码很全，自己写的。(A calculator to realize, Math, etc., suitable for beginners to learn, the code is all that he wrote.)

复数的四则运算完整版，包括加减乘除，阶乘，开方等。。。(The plural arithmetic full version,, including addition, subtraction, multiplication, and division factorial, prescribing, etc...)

卡尔曼滤波程序，两变量滤波；正弦信号跟踪；卡尔曼差分到状态方程的转换；卡尔曼同滑动平均比较(Kalman filtering process, the two variable filter sinusoidal signal tracking Kalman differential equation of state of the conversion Kalman compared with moving average)

格子玻尔兹曼 圆柱绕流 Python编写(lattice boltzmann flow around a cylinder, using Python. very fast because of numpy library)

非定常导热，附件包含3个源代码。分别对应着FTCE、BTCS和紧致格式的程序代码(unsteady conduction)

fft傅里叶快速变化程序，里面说的很清楚，很使用。(FFT Fourier rapid change program, which made it very clear, is to use. )

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.)

基于混沌理论进行数据预测的程序，欢欢迎需要的朋友参考下载，并提出修改意见 (, Please feel welcome the reference to a friend download data to predict the process based on chaos theory, and suggest modifications)

潮流调和分析程序，非常实用，里面有说明文件，基本原理是采用最小二乘法来求解超定矩阵，各种参数用来控制选择分潮，间隔时间等。(harmonic analysis)

使用JAVA模拟FFFT算法 快速傅里叶算法 (Use JAVA simulation FFFT algorithm Fast Fourier Transform Algorithm)
