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。 QB3vp4pBg@ [.ya&E)x 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: __B`0t enableservice('AutomationServer', true) p'@|Oq& enableservice('AutomationServer') Bsr;MVD u;@~P 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。 F=T};b H!H&<71- 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: pUp&eH 1. 在FRED脚本编辑界面找到参考. }3%L3v& 2. 找到Matlab Automation Server Type Library ftaGu-d% 3. 将名字改为MLAPP obRYU|T 9Q*T'+V +mgm39 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。 ff{L=uj uT\|jv, 图 编辑/参考 \vKKq/f VuU{7: 现在将脚本代码公布如下,此脚本执行如下几个步骤: o+}>E31a 1. 创建Matlab服务器。 sYMgi D 2. 移动探测面对于前一聚焦面的位置。 GC#s;X 3. 在探测面追迹光线 }{oZdO 4. 在探测面计算照度 `]T#uP<u 5. 使用PutWorkspaceData发送照度数据到Matlab ],?$& 6. 使用PutFullMatrix发送标量场数据到Matlab中 p-qt?A 7. 用Matlab画出照度数据 9/yE\p. 8. 在Matlab计算照度平均值 yJ0q)x sS 9. 返回数据到FRED中 ^8z~`he=_J U8||)+ 代码分享: y;$
