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。 a;8q7nC :[A>O( 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: dJ#mk5=
" enableservice('AutomationServer', true) IXc"gO enableservice('AutomationServer') F=bX\T7 \%g#
__\ 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。 fIWOo >)D &3#19v7/ 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: EA) K"C 1. 在FRED脚本编辑界面找到参考. n j0! 2. 找到Matlab Automation Server Type Library H}Z\r2 3. 将名字改为MLAPP RutRA <xv@us7 ezS@LFaA 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。 =^%#F~o: -T$%MX 图 编辑/参考 _=S4H {)=h 现在将脚本代码公布如下,此脚本执行如下几个步骤: 6R1}fdHvP 1. 创建Matlab服务器。 2 ,RO 2. 移动探测面对于前一聚焦面的位置。 AR8zCKBc^ 3. 在探测面追迹光线 C3>&O?7J*7 4. 在探测面计算照度 ;n`SF~CU 5. 使用PutWorkspaceData发送照度数据到Matlab %PW_v~sg 6. 使用PutFullMatrix发送标量场数据到Matlab中 x/7kcj!O 7. 用Matlab画出照度数据 Hwiw:lPq`E 8. 在Matlab计算照度平均值 ,}?x!3 9. 返回数据到FRED中 D;nm~O%
