简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 ~ :R4))qpg tzx:* 配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： B/kcb(5v enableservice('AutomationServer', true) :zRB)hd enableservice('AutomationServer') k?!TjBKm  oiIt3<BX 结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 dO Y lI`4 bkJwP s 在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： ?*B;514 1. 在FRED脚本编辑界面找到参考. = ?y^O0v 2. 找到Matlab Automation Server Type Library _SU,f> 3. 将名字改为MLAPP Ir'DA_.. @G^j8Nl+J} 37.) @ 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 WBIQ%XB ' 5%vP~vy_} 图 编辑/参考 O ~7p^i} ! hOOpZ f7 现在将脚本代码公布如下，此脚本执行如下几个步骤： +H5 jRw 1. 创建Matlab服务器。 0Og/47dO.2 2. 移动探测面对于前一聚焦面的位置。 |:`?A3^m# 3. 在探测面追迹光线 PX+"" # 4. 在探测面计算照度 #JX|S'\x 5. 使用PutWorkspaceData发送照度数据到Matlab D 3,t6\m 6. 使用PutFullMatrix发送标量场数据到Matlab中 ylo]` Nq 7. 用Matlab画出照度数据 PW(_yB; 8. 在Matlab计算照度平均值 P}w^9=;S 9. 返回数据到FRED中 7$E2/@f BxW||O|_N" 代码分享： > 2!^ dT^D $D0)j(v Option Explicit ^hGZVGSv }W Bm%f Sub Main fSgGQ
