说明：  基于相位一致的边缘检测算法，matlab源代码(Based on the same edge detection algorithm phase, matlab source code)

利用matlab的simulink工具进行最优化的设计，谢谢(Presentation and demo files for MathWorks webinar "Introduction to Simulink Design Optimization)

说明：  多变量寻优的源码，包括基本算法如下：DFP法（又称变尺度法），BFS法、一阶梯度法，共扼梯度法。(multivariate optimization of the source code, including basic algorithm is as follows : DFP Act (also known as the variable scale), BFS, a ladder degrees, a total of the accused gradient method.)

采用的是通用的平面波展开法,旋转机械二维全息谱计算，含噪脉冲信号进行相关检测。( Using common plane wave expansion method, Rotating machinery 2-d holographic spectrum calculation, Noisy pulse correlation detection signal.)

说明：  本案例研究的目的是开发一种简单而有效的半隐式傅里叶光谱算法，用于相位场晶体模型的变形研究(The purpose of this case study is to develop a simple and effective semi-implicit Fourier spectral algorithm for the deformation study of phase field crystal models)
