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。 8T92;.~( gS4zX>rqe 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: 35z]pn%L enableservice('AutomationServer', true) ]'V8{l enableservice('AutomationServer') 95Bw;U3E Uo v%12 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。 ?g%5 d /]"&E"X" 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: :,"dno7OQ 1. 在FRED脚本编辑界面找到参考. t+Kxww58 2. 找到Matlab Automation Server Type Library 9 tkj:8_ 3. 将名字改为MLAPP LSb3w/3M =BQM(mal _H}y7 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。 r|4jR6%<'m 6~zR(HzV{ 图 编辑/参考 j)ZvlRi, SY|r'8Z%Q 现在将脚本代码公布如下,此脚本执行如下几个步骤: pxjN\q 1. 创建Matlab服务器。 +Q_(wR"FS 2. 移动探测面对于前一聚焦面的位置。 6l&m+!i 3. 在探测面追迹光线 ]\5@N7h 4. 在探测面计算照度 fgg^B[(Y 5. 使用PutWorkspaceData发送照度数据到Matlab <_@ K4zV 6. 使用PutFullMatrix发送标量场数据到Matlab中 Q1EY!AV8 7. 用Matlab画出照度数据 4r#O._Z 8. 在Matlab计算照度平均值 6la# 0U23 9. 返回数据到FRED中 u\=gps/Z _d6mf4M]5 代码分享: loN!&YceW ='u'/g$'& Option Explicit f gI.q iz]Vb{5n% Sub Main E{gu39 D h
