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。 +F6_P -v2q:x'G# 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: ~#Mx&mZ enableservice('AutomationServer', true) `cRB!w=KHV enableservice('AutomationServer') )}lV41u M- A}(r +J 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。 Y3&ecEE K?I&,t_*R 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: Kt0Tuj@CY 1. 在FRED脚本编辑界面找到参考. *a.*Ha 2. 找到Matlab Automation Server Type Library +Ea XS 3. 将名字改为MLAPP )o,0aGo>Of Rb*\A7o|; W.<<azi 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。 ^!tI+F{n{ fL:Fn"Nv 图 编辑/参考 tfQq3 # ?5gpk1 现在将脚本代码公布如下,此脚本执行如下几个步骤: _L.yt5_ 1. 创建Matlab服务器。 U$Z}<8 2. 移动探测面对于前一聚焦面的位置。 N/=3Bs0y- 3. 在探测面追迹光线 e@By@r&nql 4. 在探测面计算照度 K>6p5*& 5. 使用PutWorkspaceData发送照度数据到Matlab H|O}Dsj 6. 使用PutFullMatrix发送标量场数据到Matlab中 u'."E7o# 7. 用Matlab画出照度数据 Puh&F< B 8. 在Matlab计算照度平均值 R:p,Hav<q 9. 返回数据到FRED中 3I(M<sB} 9mm(?O~'p 代码分享: </p.OaNe -/?<@*n Option Explicit '+wTrW m~j z w9r0bG Sub Main RMXj)~4. dG+xr!
