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。 H C,5j)1 6"Lyv 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: he/rt# enableservice('AutomationServer', true) .ahY 1CO enableservice('AutomationServer') pdER#7Tq -s!J3DB 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。 .P7q)lj36h (9ZW^flY 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: R9^vAS4t[O 1. 在FRED脚本编辑界面找到参考. 7w" !"W# 2. 找到Matlab Automation Server Type Library (T$cw(! 3. 将名字改为MLAPP ;dMr2y`6 H! 5Ka#B y9]7LETv\M 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 aMGh$\Pg G7|d$!% 图 编辑/参考 ,/GFD[SQ \m}a%/ 现在将脚本代码公布如下,此脚本执行如下几个步骤: );AtFP0Y 1. 创建Matlab服务器。 =OtW!vx#R. 2. 移动探测面对于前一聚焦面的位置。 Jk`Jv; 3. 在探测面追迹光线 llR5qq=t 4. 在探测面计算照度 /Dd x[P5p= 5. 使用PutWorkspaceData发送照度数据到Matlab 9eq)WI/ 6. 使用PutFullMatrix发送标量场数据到Matlab中 j^8HTa0Cy| 7. 用Matlab画出照度数据 Og1\6Q 8. 在Matlab计算照度平均值 H_3WxfO 9. 返回数据到FRED中 h lc!}{$%8 X_nbNql 代码分享: R!7--]Wcg ,1B4FAR& Option Explicit :UH*Wft1 dc4XX5Z Sub Main "Dk@-Ac qi7*Jjk>90 Dim ana As T_ANALYSIS rA8NE> Dim move As T_OPERATION T"3LO[j+ Dim Matlab As MLApp.MLApp 5wh(Qdib Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long @
