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。 $5>x)jr:w+ dBW#PRg 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： +,9Muf h enableservice('AutomationServer', true) uYc&Q $U enableservice('AutomationServer') \<y#$:4r<8  ;[Hrpl
S 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。 8ZO~=e .q$/#hN:e 在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： KV'-^\ 1. 在FRED脚本编辑界面找到参考. @gJPMgF$F 2. 找到Matlab Automation Server Type Library i{>YQ 3. 将名字改为MLAPP WF <*rl Q9t.*+ i"hn%u$V 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 OL#RkD W @FGU 图 编辑/参考 #kQLHi3## DAd$ u1 现在将脚本代码公布如下，此脚本执行如下几个步骤： V H.}}R S% 1. 创建Matlab服务器。 Wy$Q!R =i 2. 移动探测面对于前一聚焦面的位置。 2l4`h)_q 3. 在探测面追迹光线 5c l%>U 4. 在探测面计算照度 5wMEp" YHE 5. 使用PutWorkspaceData发送照度数据到Matlab m^,3jssdA 6. 使用PutFullMatrix发送标量场数据到Matlab中 ;V1e>?3 7. 用Matlab画出照度数据 O,KlZf_B 8. 在Matlab计算照度平均值 UX<0/"0h 9. 返回数据到FRED中 gH/k}M7tA# UI w6~a3E 代码分享： , On u% V{kgD pB Option Explicit rYr. mX *|:]("i Sub Main = G 3A} p&;,$KDA Dim ana As T_ANALYSIS h'G8@j; Dim move As T_OPERATION q0
