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。 ~]uZy=P? 5 uDayBaR 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: Q\kub_I{@ enableservice('AutomationServer', true) 1 W'F3 enableservice('AutomationServer') l@~LV}BI \#dl6:" 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。 l1+[ `/Y+1 aD 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: \ijMw 1. 在FRED脚本编辑界面找到参考. c3xl9S,5 2. 找到Matlab Automation Server Type Library Hs0pW5oZ 3. 将名字改为MLAPP BC/_:n8O 1n%8j*bJq )\ 0F7Z 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。 9dKul,c 8SmjZpQ? 图 编辑/参考 SR7j\1a/2A RKTb'3H 现在将脚本代码公布如下,此脚本执行如下几个步骤: /-Qv?" 1. 创建Matlab服务器。 OX hAha`R 2. 移动探测面对于前一聚焦面的位置。 cF+ X,]=6 3. 在探测面追迹光线 d"THt} 4. 在探测面计算照度 G?hK9@ |v 5. 使用PutWorkspaceData发送照度数据到Matlab &M"ouy Zo9 6. 使用PutFullMatrix发送标量场数据到Matlab中 [}o~PN:sT( 7. 用Matlab画出照度数据 <GIwRVCU 8. 在Matlab计算照度平均值 s&
