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。 -X3CrW RjR+'<7E^ 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: sGh TP/ enableservice('AutomationServer', true) \tA@A enableservice('AutomationServer') i~3\dp "yl6WG#J 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。
#Zi6N C>F5=& 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: .yHK 1. 在FRED脚本编辑界面找到参考. 99%R/m 2. 找到Matlab Automation Server Type Library ^E)8Sb9t 3. 将名字改为MLAPP ` +)Bl%* ~@e=+Z %s ;5 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。 A'"J'q*t 4q?R 3\e; 图 编辑/参考 Zqv n0t+xvNDF_ 现在将脚本代码公布如下,此脚本执行如下几个步骤: LoSrXK~0~J 1. 创建Matlab服务器。 \^!<Y\\ 2. 移动探测面对于前一聚焦面的位置。 1;!dTh 3. 在探测面追迹光线 uc\G)BN 4. 在探测面计算照度 c Y+n 6k5 5. 使用PutWorkspaceData发送照度数据到Matlab `uqe[u;`6 6. 使用PutFullMatrix发送标量场数据到Matlab中 4F<was/ 7. 用Matlab画出照度数据 $7-S\sDr 8. 在Matlab计算照度平均值 e&K7n@ 9. 返回数据到FRED中 9JeT1\VvHY m63>P4h? 代码分享: VMS3Q)Ul di]CYLf Option Explicit l\2"u M#7 <e wcWr Sub Main _`Y%Y6O1/ 7#*`7 K'P!
