描述高斯光束经过透镜的变换规律，GUI界面，可以计算不同的倾斜角情况下的像散情况 (Describe the transformation law of gaussian beams through a lens, the GUI interface, you can calculate different Angle of astigmatism)

This submission contains an interface to a LBFGS-code for unconstrained minimization problems of the form min_{x} f(x) + c*| ilde{x}|, where x are the parameters, f is a scalar valued real function, c is a positive scalar (default value=0), |.| denotes the 1-norm, and ilde{x} is some subset of the parameters x.

模糊PID调节，并且通过与普通PID调节对比得出较好的效果(Fuzzy PID control, and by contrast with the ordinary PID regulator obtained better results)

自适应子空间辨识，通过输入输出数据，计算状态空间方程，建模并预测。(Adaptive subspace identification, through input and output data, calculates the state space equation, modeling and forecasting.)

三维子空间music 方位角定义为与x轴的夹角，俯仰角定义为与z轴之间的夹角,俯仰角在0—90度，方位角0-180. 分辨不相关的两个角成功概率/估计偏差与SNR 最后进行谱峰搜索(Dimensional subspace music is defined as the angle and azimuth angle, pitch angle is defined as the x-axis and z-axis between the pitch angle of 0-90 degrees in azimuth 0-180 distinguish two unrelated probability of success angle/estimation error and SNR Finally peak search)

The effects of this propeller torque are usually relatively minor. If unaccounted for, the propeller torque will cause a slow rolling motion in the direction opposite the propeller rotation
