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。 -yB}(69 o5p{ O>D[z 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： L /:^;j`c enableservice('AutomationServer', true) ]:#=[ CH enableservice('AutomationServer') y~\ujp_5 w  Y ~g\peG7 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。 cz,QP'g 1$eoW/8. 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： _Iminet 1. 在FRED脚本编辑界面找到参考. pH mqwB~| 2. 找到Matlab Automation Server Type Library Nd]F 33| X 3. 将名字改为MLAPP 4/|x^Ky>G kBhjqI* 5 "@>>"3U 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。 ?tY+P`S Et!J*{ s 图 编辑/参考 jQ;/ =9 u+Ix''Fn#% 现在将脚本代码公布如下，此脚本执行如下几个步骤： )I[f(f%W7 1. 创建Matlab服务器。 ~;3#MAG 2. 移动探测面对于前一聚焦面的位置。 L&DjNu`!9 3. 在探测面追迹光线 h\ UKm|BZ 4. 在探测面计算照度 m{Vd3{H40 5. 使用PutWorkspaceData发送照度数据到Matlab 2PYn zAsl 6. 使用PutFullMatrix发送标量场数据到Matlab中 mP &\? 7. 用Matlab画出照度数据 {o5|(^l 8. 在Matlab计算照度平均值 O\.^ H/ 9. 返回数据到FRED中 !h4T3sO y
