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。 J<"K`|F hdx_Tduue 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: Ja:4EU$Lu enableservice('AutomationServer', true) 1>rQ).eT enableservice('AutomationServer') #$xtUCqX O}zHkcL 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。 j0}wv~\ i@nRZ$ K 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: UTh2?Rh/ 1. 在FRED脚本编辑界面找到参考. x5uz$g 2. 找到Matlab Automation Server Type Library #%k_V+o3 3. 将名字改为MLAPP 2=fM\G DdI%TU K, f&4+-w.: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。 DSqA}r :XFQ}Cl 图 编辑/参考 'Xwv, 0.x+ H9z 现在将脚本代码公布如下,此脚本执行如下几个步骤: =K} Pfh 1. 创建Matlab服务器。 y/Y}C.IWp) 2. 移动探测面对于前一聚焦面的位置。 'RKpMdoz 3. 在探测面追迹光线 8xAI n>,_ 4. 在探测面计算照度 W7WHDL^ 5. 使用PutWorkspaceData发送照度数据到Matlab / ^d9At614 6. 使用PutFullMatrix发送标量场数据到Matlab中 A?#i{R 7. 用Matlab画出照度数据 4AJT)I. 8. 在Matlab计算照度平均值 Nmz5:Rq 9. 返回数据到FRED中 t;VMtIW+E fVgK6?<8^ 代码分享: w/o^OjwQ [k\VUg:P Option Explicit aSIb0`(3 Yv]vl6< Sub Main ]^>Inh!
