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。 z 1.vnGP bJw{ U. 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： /
w[Tu enableservice('AutomationServer', true) 3 k/X;:,. enableservice('AutomationServer') /#?! 9c  fd&>p 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。 Q0g^% CWb*bw0 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： I(z16wQ 1. 在FRED脚本编辑界面找到参考. #f_. 2. 找到Matlab Automation Server Type Library 3A.lS+P1 3. 将名字改为MLAPP s+h}O}RV Bt(nm> Ng uu/2C \n} 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。 o76{;Bl\ O : xY9eq= 图 编辑/参考 ghTue*A K :>O X 现在将脚本代码公布如下，此脚本执行如下几个步骤： '{)Jhl47 1. 创建Matlab服务器。 M5N #xgR 2. 移动探测面对于前一聚焦面的位置。 ^3QJv{)Q 3. 在探测面追迹光线 t"v kd 4. 在探测面计算照度 7s Gf_`Z 5. 使用PutWorkspaceData发送照度数据到Matlab N_l_^yD 6. 使用PutFullMatrix发送标量场数据到Matlab中 F4IU2_CnPD 7. 用Matlab画出照度数据 <driD'=F 8. 在Matlab计算照度平均值 k =O 9. 返回数据到FRED中 v z&88jt 4v9d&
