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。 G;G*!nlWf G&g;R OgY 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： kg7F8($ enableservice('AutomationServer', true)
/:4J enableservice('AutomationServer') )/$J$'mcxd  c,~uurVi 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。 3U@jw,K!{A )[Tm[o?Y. 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： 2X@9o4_4q 1. 在FRED脚本编辑界面找到参考. #Q8_:dPY 2. 找到Matlab Automation Server Type Library ?Ij(B}D 3. 将名字改为MLAPP f CU] Zd[rn:9\ =GX5T(P8k 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。 +; KUL6 Ib# -M;{ 图 编辑/参考 f8:nKb>nq$ 5^g* 现在将脚本代码公布如下，此脚本执行如下几个步骤： ,<Q 1. 创建Matlab服务器。 HoGYgye= 2. 移动探测面对于前一聚焦面的位置。 ,>a!CnK= 3. 在探测面追迹光线 loVg{N : 4. 在探测面计算照度 wXQxZuk[ 5. 使用PutWorkspaceData发送照度数据到Matlab kK[4uQQ 6. 使用PutFullMatrix发送标量场数据到Matlab中 N#T'}>t y 7. 用Matlab画出照度数据 J\@6YU[A 8. 在Matlab计算照度平均值 Ou_H& R 9. 返回数据到FRED中 ^1S{:: &>JP.//spi 代码分享： zC2:c"E
