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。 FVHL;J]nf1 0;9LIL5 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: e)M1$ enableservice('AutomationServer', true) M:~#"lfK enableservice('AutomationServer') [,c>-jA5 QB7<$Bp 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。 >_o_&;=`v oUqNA|l
T 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: Ok@5`?08 1. 在FRED脚本编辑界面找到参考. AG?oA328 2. 找到Matlab Automation Server Type Library VC@o]t5 3. 将名字改为MLAPP @AwH?7(b Ez)Go6Q g!8-yri 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。 A6d+RAx e:#\Oh 图 编辑/参考 p=zjJ~DVd ??F{Gli"C` 现在将脚本代码公布如下,此脚本执行如下几个步骤: ^6=nL<L 1. 创建Matlab服务器。 q#Bdq8 2. 移动探测面对于前一聚焦面的位置。 xc!"?&\* 3. 在探测面追迹光线 ;tHF$1!J 4. 在探测面计算照度 *(rq AB0~ 5. 使用PutWorkspaceData发送照度数据到Matlab #pZ3xa3R 6. 使用PutFullMatrix发送标量场数据到Matlab中 gP}M\3-O 7. 用Matlab画出照度数据 '&`Zy pq 8. 在Matlab计算照度平均值 }*%%GPJ 9. 返回数据到FRED中 ^^v!..V]J bV"0}|A~K 代码分享: gG}<l ': b@7
