single phase active harmonic filter

主要用于计算目标前向、侧向、后向散射特征，同时完成RCS极坐标图的绘制(Used to calculate the target forward, sideways, backward scattering, and complete the drawing of the polar diagram RCS)

对一个信号文件导入并进行fft变换，显示图形；对信号是否平稳，周期性，采样点数N，有偏无偏处理的估计效果等都做了处理和显示(A signal file is imported and transformed by FFT to display graphics; whether the signal is stable, periodic, sampling point N, the estimation effect of biased and unbiased processing are processed and displayed.)

最优化理论中的几个算法，包括共轭梯度法，公轭梯度法，方向加速法，步长加速，变尺度法(Optimization theory in several algorithms, including the conjugate gradient method, public and conjugate gradient method, directional method, step speed, variable metric method)

通过编写该程序，实现图像的动态分形处理及仿真。(Through the preparation of the program, the image of the dynamic fractal processing and simulation.)

程序为自适应有限元法求解抛物型方程，都是matlab语言编写(Adaptive fenite element method solver for Parabolic equation. )

常用的DEA交叉模型，是目前广泛使用的效率评价模型之一(DEA crossover model, which is commonly used in DEA crossover model, is one of the most widely used efficiency evaluation models at present.)

铰链四杆机构的程序，用于计算其各构件的角位移、角速度、角加速度等变化情况(Hinge four-bar mechanism for calculating the angular displacement, angular velocity, angular acceleration and other changes of its components)
