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。 T$&vk#qr {;^GKb+ 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: Lyy:G9OV enableservice('AutomationServer', true) /$=<RUE enableservice('AutomationServer') mrGfu:r `7$Sga6M 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。 UPGS/Xs]1 MY>*F[~ 2 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: (/e[n.T 1. 在FRED脚本编辑界面找到参考. ?d5_{*]+v 2. 找到Matlab Automation Server Type Library "59"HVV 3. 将名字改为MLAPP *Kmo1>^ Zk<Y+! {osadXdC 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。 \]Y=*+{ Dk#4^`qp1 图 编辑/参考 }Q-%ij2 5}|bDJ$% _ 现在将脚本代码公布如下,此脚本执行如下几个步骤: fI"OzIJV 1. 创建Matlab服务器。 iL8:I)z 2. 移动探测面对于前一聚焦面的位置。 8o\KF(I 3. 在探测面追迹光线 I/k/5 4. 在探测面计算照度 2=`}:&0l 5. 使用PutWorkspaceData发送照度数据到Matlab mXJ`t5v^l 6. 使用PutFullMatrix发送标量场数据到Matlab中 6|B;C 7. 用Matlab画出照度数据 |,lw$k93 8. 在Matlab计算照度平均值 _BPp=(| 9. 返回数据到FRED中 v&3 Oc `-yiVUp1:z 代码分享: !JnxNIr&i| ?!;i/h*{ Option Explicit wfq}NK; 01">$ Sub Main 4#&w-W Z11I1)%s Dim ana As T_ANALYSIS /"
