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。 ub,Sj{Mq" N<N!it 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: x:sTE u@ enableservice('AutomationServer', true) ]lZ!en enableservice('AutomationServer') tQ?? nI2 #Fu OTBNvB 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。 E@t~juF! l6l)M 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: ~73YOGiGJH 1. 在FRED脚本编辑界面找到参考. zpg*hlv 2. 找到Matlab Automation Server Type Library }p8a'3@Z 3. 将名字改为MLAPP KS(s<ip| g<UjB Z[0xqGYLB 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。 Wv(VV[?/& i/)Uj-*G) 图 编辑/参考 }4eSB s|EP/=9i 现在将脚本代码公布如下,此脚本执行如下几个步骤: \i`/k( 1. 创建Matlab服务器。 n6L}#aZG 2. 移动探测面对于前一聚焦面的位置。 )W*S6}A 3. 在探测面追迹光线 eT}c_h) 4. 在探测面计算照度 HlI*an 5. 使用PutWorkspaceData发送照度数据到Matlab "hs`Y4U
