采用谐波叠加法模拟风速，计算时间较长，但精度较高。(The use of harmonic superposition method simulated wind speed, computational time, but the accuracy is higher.)

high pass filter with FIR for education

有限元分析优化，主要基于水平集方法，comsol的二次matlab开发(Finite element analysis and optimization, mainly based on the level set method, comsol matlab development of secondary)

基于MATLAB实现了极坐标下的傅里叶变换，对一个给定 n×n 的二维信号，其计算复杂度等价于笛卡尔坐标下的2D-FFT，可广泛应用于图像处理和分析。(A fast high accuracy Polar FFT algorithm is given in the software package written in MATLAB. For a given 2D signal of size n×n, the algorihtm s complexity is just like in a Cartesian 2D-FFT, which can be used widely in image processing and analysis.)

The program computes and plots the equation of time, the declination, and an analemma curve for various orbital parameters. The analemma is the curve traced by the position of the sun, measured at clock noon, over a year.
