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。 /AoVl'R `|uoqKv 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: 5nY9Ls(e enableservice('AutomationServer', true) mQFa/7FX enableservice('AutomationServer') Wf_CR( 8~}s 3j4 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。 H'D#s;SlR `~0P[>|+ 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: p EY>A_F 1. 在FRED脚本编辑界面找到参考. +tPx0>p; 2. 找到Matlab Automation Server Type Library m\/>C|f\ 3. 将名字改为MLAPP dEL3?-;' KU*`f{| uSH>$;a 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。 qjJ{+Rz2 2B5A!?~> 图 编辑/参考 2\DTJ`Y, Al=(sHc' 现在将脚本代码公布如下,此脚本执行如下几个步骤: ~v^%ze 1. 创建Matlab服务器。 jC#`PA3m= 2. 移动探测面对于前一聚焦面的位置。 `Fz\wPd 3. 在探测面追迹光线 / *AJ+K._ 4. 在探测面计算照度 v/]Qq 5. 使用PutWorkspaceData发送照度数据到Matlab te4F"SEf 6. 使用PutFullMatrix发送标量场数据到Matlab中 ]Jja 7. 用Matlab画出照度数据 _E3U.mV 8. 在Matlab计算照度平均值 LG"c8Vv&)~ 9. 返回数据到FRED中 -mE n9N#&Q"7m
