这个Matlab程序利用0~255灰度色彩表示涡旋光束的相位分布，能够根据需求绘制任意阶数的涡旋光相位分布。

近年来，涡旋光束由于在囚禁和操控原子及其他微粒中的应用而引起了不少关注和研究。涡旋光束在光束的传播方向上有一个位相项e(ilθ)，而且它拥有一个光束轨道角动量。该MATLAB程序实现了从一个高斯基模变换到涡旋光束的基本功能。

C. Qian, X. Fu, N.D. Sidiropoulos, L. Huang, and J. Xie explore phase retrieval in the presence of outliers in their paper published in the IEEE Transactions on Signal Processing. Typically, phase retrieval algorithms perform well under Gaussian noise; however, their performance severely degrades wi

该程序生成一个图形，用于说明相位干涉测量，其中一个辐射(E,B)在远场区被认为准时的电磁源正以传感器间距的半波长d=λ/2撞击N个元件的均匀线性阵列。在该图中，注意到了连续的相位delta_i，以及阵列的辐射方向图被描述为E(theta)，因此该图可用于课程、演示或科学论文。

在本示例中，Matlab代码实现了非线性求解器，用于模拟多Kong介质中的流动。代码使用牛顿-拉夫森法求解方程f(x) = 0，基本步骤如下： 初始化x0。 计算更新：x1 = x0 - f(x0) / f'(x0)。 构建矩阵形式：A = df1/dx1 ... dfN/dxN，b = -f1 ... -fN。 解线性方程Ax = b，更新x = x + alpha * dx（对于非阻尼情况，alpha = 1）。 计算残差|f + f'dx| / |f|，检查收敛性。

MATLAB development focuses on single-phase rectifiers. This includes the simulation of single-phase bridge rectifiers with filter capacitors and the analysis of third harmonic distortion.

This three-phase asynchronous motor servo control simulation provides a MATLAB source file that can be executed directly. With this simulation, users can observe the dynamic response and control characteristics of three-phase asynchronous motors under servo control, making it ideal for educational a

The Single-Phase SPWM Inverter is modeled using Simulink. This approach is particularly easy for beginners to understand and implement. By using Simulink, users can create a single-phase SPWM inverter that simulates the pulse-width modulation (PWM) technique for controlling the inverter's output vol
