SPSO基本算法，有详细的解释，适用于初学者！(The SPSO basic algorithm, detailed explanations, suitable for beginners!)

深度学习的一些工具包和一些例程，有关于BP神经网络，卷积神经网络等。用于熟悉相关算法基本够用。比较适合想了解此类内容的初学者。(Some Tools of deep learning. Eg:NN,CNN,BP and so on. It s pretty well to student.)

采用专家PID控制器解决三阶传递函数的阶跃响应(PID controller using expert to solve the third-order transfer function of the step response)

如上图所示，定向耦合器由完全相同的直波导与弯曲波导构成，波 导芯为宽高比相同（均为 a） 的正方形， 其工作波长，波导材料 对 TE 模式的折射率，及圆弧形弯曲波导的半径 r 等参数如图所 示，若波长为 1550 nm， 归一化光功率为 1 的光波从直波导输 入，请选择适当的满足单模工作的波导宽度 a， 然后给出从圆形弯 曲波导输出的归一化光功率 P4与两波导边缘的间距 d(Directional coupler by the same straight and curved waveguides constituting the waveguide, waves Conducting core is the same aspect ratio (are a) square, its operating wavelength, the waveguide material The refractive index of the TE mode and the arc-shaped curved waveguide of radius r and other parameters as shown Shown, if the wavelength of 1550 nm, normalized optical power a light straight waveguide input In, the appropriate work to meet the single-mode waveguide width a, and then is given a circular bend Curved waveguide output normalized optical power P4 and two edges of the waveguide spacing d)
