Arithmetic

This code is about migration of seismic data.

说明：  车间布局优化模型是一个含有较为复杂约束的非线性连续优化模型，可以使用遗传算法进行优化。(Workshop layout optimization model containing is a complicated nonlinear optimization model in a row, you can use the genetic algorithm optimization. )

透视变换的程序，一个很好的透视变换程序，希望大家下载(Perspective transformation process, a very good perspective transformation process, I hope you download)

说明：  数学形态滤波器用于旋转机械的振动信号的降噪(Morphological noise filter for rotating machinery vibration signals)

采用各种不同的方法实现PCA，包括truePCA,empca等，做主成份分析好方法！(adopted various methods to achieve the PCA, including truePCA, empca. element analysis comes good way!)

数字信号处理中数字滤波器的设计及对其滤波使用(Digital signal processing in the digital filter design and its use filtering)

matlab中运用hough变换，设定恰当的阈值，将超过阈值的点在三维空间标示出来&将三维参数矩阵根据半径的不同做成不同的帧，制作成视频(hough transform matlab in use, set the appropriate threshold, will exceed the threshold point in three-dimensional space marked out & three-dimensional parameter matrix made of different frames depending on the radius, made into video)

计算轨道角动量的纯度,解调的纯度分布情况存到一个用户自定义的TXT文档中(Calculate the purity of orbital angular momentum )
