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[7U>q[E :yO)g]KF 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: _:TD{ EO$ enableservice('AutomationServer', true) :k JSu{p enableservice('AutomationServer') <Q%o}m4Kt G*n5`N@>7 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。 O/Da8#S< gmrjCLj 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: rYc?y 1. 在FRED脚本编辑界面找到参考. lMlXK4- 2. 找到Matlab Automation Server Type Library VCh%v -/ 3. 将名字改为MLAPP Yr[1-Oy/k dmf~w_(7 .*v8*8OJ& 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。 [=XsI]B\ 3"q%-M|+Q 图 编辑/参考 ZfMJU `<[Zs]Fe4 现在将脚本代码公布如下,此脚本执行如下几个步骤: 2< ^B]N 1. 创建Matlab服务器。 <m9IZIY< 2. 移动探测面对于前一聚焦面的位置。 D<nTo&m_ 3. 在探测面追迹光线 U4Qc$&j> 4. 在探测面计算照度 Vrz<DB^-e 5. 使用PutWorkspaceData发送照度数据到Matlab Ei}B9 &O 6. 使用PutFullMatrix发送标量场数据到Matlab中 @8Co5`CVl 7. 用Matlab画出照度数据 )M}bc1 _ 8. 在Matlab计算照度平均值 rMLCtGi 9. 返回数据到FRED中 cC>.`1: *}yW8i}36 代码分享: I_N"mnn@Nr 0*h\/!e Option Explicit 5$N4<Lo7 -O -_F6p'D Sub Main {T=I~#LjMI l HZf'P_Wx Dim ana As T_ANALYSIS V18w Dim move As T_OPERATION t t#M4n@ Dim Matlab As MLApp.MLApp T w/CJg
