Simulation of AR process

本案例为不等式约束最优化问题，采用罚函数法（内点法）。具体求解过程是用MATLAB编程求解的。(The Case for inequality constrained optimization problem using penalty function method (interior point method). Specific solution process is solved using MATLAB programming.)

说明：  Transformation from XYZ coordinates to Geodetic Coordinates.

说明：  一个用来计算一维光子晶体全息干涉分布的程序，很好用的！(Used to calculate a one-dimensional photonic crystal holographic interferometry distribution procedures, very good use!)

本文件主要内容是讲解关于matlab中对矩阵的运算等等(MATLAB matrix calculator)

说明：  利用matlab中随机森林工具包数据进行预测(RF toolkit data in matlab was used for prediction)

说明：  该程序编写了四束光干涉形成三维全息光子晶体的图(The procedure to prepare a four-beam interference in the formation of three-dimensional holographic photonic crystal of Figure)
