  • LinearBPM
    这是一个简单的FFT为无电位1 +1 +1 Ð 薛定谔方程的光束传播方法。如果该软件灵活,允许引入的术语(如果是极少数需要包括色散效应高阶导数)。例如,如果一个人渴望解决的一个方程的形式: (四/ dz的+ Ð ^ 2/dx ^ 2 - 0.25 * Ð ^ 3/dx ^ 3)== 0 Ÿ 它可以解决使用以下代码: Ž = linspace(0,1,512) x = linspace(-5,5,1024) psi0 =进出口(- x的。^ 2) Ð = D_lateral1D(十,2)-0.25 * D_lateral1D(十,3) 字段= LinearBPM(psi0,有D,Z) 凡D_lateral1D是一个函数,提供“取代”的微分算子。 这个函数是在一个非线性的BPM,我曾对(分步,谱方法等),将提交给我,当我完成他们的文件和组织功能更复杂的设置非常初期阶段。 (This is a simple FFT based beam propagation method for potential-free 1+1+1D Schrodinger equation. The software if flexible and allows to introduce high-order derivatives in the term (very handful if is needed to include dispersion effects). For example, if one desires to solve an equation in the form: (d/dz+ d^2/dx^2- 0.25*d^3/dx^3)Y == 0 It can be solved using the following code: z=linspace(0,1,512) x=linspace(-5,5,1024) psi0=exp(-x.^2) D=D_lateral1D(x,2)-0.25*D_lateral1D(x,3) field=LinearBPM(psi0,D,z) Where D_lateral1D is a provided function that "replaces" the derivative operator. This function is a very early stage in a more complex set of non-linear BPM functions that I have made (split-step, spectral methods, etc.) and I will submit them when I finish their documentation and organization. Sorry for my English, I m eager for your comments. )

    一共5个代码,其中aufgabe和lms的功能是输入一个脉冲信号,根据不同的系统参数,得出输出信号。 cordic是一个算角度旋转的方法。 gray和graydecode是输入一个数字,对应输出每次只变一位的2进制输出信号。 因为我还是个学生,可能代码比较简单,希望站长谅解,谢谢!我真心希望能够成为该站的一员,学习到有用的知识。(A total of five codes, which aufgabe and lms function is a pulse input signal, depending on the system parameters, derived output signal. cordic is a rotation angle calculation method. gray and graydecode is to enter a number, corresponding to a time become an output of two binary output signals. Because I was a student, you may code for relatively simple hope that owners understand, thank you! I really hope to be a member of the station, to learn useful knowledge.)
