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。 R5O{;/w {2u#Q7]| 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: aD

{[r enableservice('AutomationServer') ?-"xP'# s)_Xj`Q# 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。 K_\fO|<k C.SGm 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: =HJ)!( 1. 在FRED脚本编辑界面找到参考. x!6&)T?!n 2. 找到Matlab Automation Server Type Library q5X\wz2N 3. 将名字改为MLAPP _Wcr'*7 H(qDQqJHYy G2#={g{ 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。 ?m&?BsW$) /I[?TsXp 图 编辑/参考 \@yx;}bdI Yh`P+L 现在将脚本代码公布如下,此脚本执行如下几个步骤: h.\V;6ly 1. 创建Matlab服务器。 b"U{@ 2. 移动探测面对于前一聚焦面的位置。 KA )9&6 3. 在探测面追迹光线 ]y*AA58; 4. 在探测面计算照度 /S29\^ 5. 使用PutWorkspaceData发送照度数据到Matlab W n*>h'R 6. 使用PutFullMatrix发送标量场数据到Matlab中 xO8-vmf2 7. 用Matlab画出照度数据 }?f%cRT$ 8. 在Matlab计算照度平均值 I@dS/ 9. 返回数据到FRED中 9
