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。 +xGz~~iNh Vy+UOV&v- 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: ueimTX k enableservice('AutomationServer', true) e1d);m$ enableservice('AutomationServer') 6X1_NbC 4R8W ot 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'BvS %b)~K|NEFf 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: (";{@a % 1. 在FRED脚本编辑界面找到参考. zc,kHO| 2. 找到Matlab Automation Server Type Library ~wX4j 3. 将名字改为MLAPP 'J0Erk8( Xfq]vQ/{ ?n]e5R(cj 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。 =2BB ~\G+ @qGg=)T 图 编辑/参考 }'o[6#_*X 74hQ?Atw: 现在将脚本代码公布如下,此脚本执行如下几个步骤: 02_37!\ 1. 创建Matlab服务器。 r]0UF0# 2. 移动探测面对于前一聚焦面的位置。 1zz.`.R2U 3. 在探测面追迹光线 g;M\4o 4. 在探测面计算照度 5[1#d\QR 5. 使用PutWorkspaceData发送照度数据到Matlab jNO8n)a&p 6. 使用PutFullMatrix发送标量场数据到Matlab中 ~w>Z !RuhT 7. 用Matlab画出照度数据 Q302!N 8. 在Matlab计算照度平均值 O8J:Tw}M* 9. 返回数据到FRED中 JN{xh0* .x^`y2'U 代码分享: e>oE{_e k*;2QED Option Explicit X?F$jX|c N$jI&SI?} Sub Main
