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。 C`0; dNL<O 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: i#%17} enableservice('AutomationServer', true) eJ23$VM+9 enableservice('AutomationServer') _v9P0W^.7 <8Zm}-U 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。 \Y{^Q7!>:8 \)Bws ` 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: j%qBNoT~ 1. 在FRED脚本编辑界面找到参考. #K3`$^0 s 2. 找到Matlab Automation Server Type Library ny]R,D0 3. 将名字改为MLAPP 1/H9(2{L xC,;IS k, :nHa-N3 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。 nd[{DF?)/ EhOy<f[4W 图 编辑/参考 dlx"L% 4/Yk;X[jk 现在将脚本代码公布如下,此脚本执行如下几个步骤: >; A7mi/ 1. 创建Matlab服务器。 kCu" G 2. 移动探测面对于前一聚焦面的位置。 G-)Q*p{i| 3. 在探测面追迹光线 `]8z]PD 4. 在探测面计算照度 18AKM 5. 使用PutWorkspaceData发送照度数据到Matlab d}.*hgk 6. 使用PutFullMatrix发送标量场数据到Matlab中 $#/-+> 7. 用Matlab画出照度数据 h8Bs=T 8. 在Matlab计算照度平均值 FesXY856E 9. 返回数据到FRED中 D# "ppa} B7fV_-p: G 代码分享: & bwhD.:= Ae0jfTv Option Explicit $dp;$X3 .qcIl)3 Sub Main VqeK~,} v?U;o&L(
