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。 p^Z|$aZZ ezhfKt]j 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: 'R#MH enableservice('AutomationServer', true) @RCZ![XYWg enableservice('AutomationServer') Dc 84^>l k4!p))ql 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 1uEM;O F3 g$b,RMH 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: z uo:yaO 1. 在FRED脚本编辑界面找到参考. |`|zo+aW 2. 找到Matlab Automation Server Type Library :OqEkh"$# 3. 将名字改为MLAPP >u|4490<0 @y6^/' 1suP7o A; 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 .3wx}!:*| |Qpd<L 图 编辑/参考 .3>q3sS feM( 现在将脚本代码公布如下,此脚本执行如下几个步骤: Yf1%7+V35 1. 创建Matlab服务器。 9)n3f^,Oj* 2. 移动探测面对于前一聚焦面的位置。 9niffq)h 3. 在探测面追迹光线 vq\L9$WJ 4. 在探测面计算照度 NFG~PZ`6R 5. 使用PutWorkspaceData发送照度数据到Matlab B- |C%~fe 6. 使用PutFullMatrix发送标量场数据到Matlab中 e5w0}/yW/ 7. 用Matlab画出照度数据 ]w]:9w 8. 在Matlab计算照度平均值 ACI.{`SrQ= 9. 返回数据到FRED中 %][zn$aa| <W^>:!?w 代码分享: n:}'f-
