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。 m#'2
3 C`D5``4 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： }XiS:
enableservice('AutomationServer', true) :G|Jcl=r enableservice('AutomationServer') Nd&u*& S  .!
LOhZ
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。 ( d[)U< pbivddi2 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： 6|05-x| 1. 在FRED脚本编辑界面找到参考. ?< Dinq 2. 找到Matlab Automation Server Type Library C,w$)x5kls 3. 将名字改为MLAPP 33\{S$p , 2)LH 'Xx }Y5Sf"~M 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。 <3QE3;4 o_<o8!]l" 图 编辑/参考 P'Jw: )k ( "6n~, $ 现在将脚本代码公布如下，此脚本执行如下几个步骤： ~_SV `io 1. 创建Matlab服务器。 KX9+*YY, 2. 移动探测面对于前一聚焦面的位置。 Q^8C*ekfg! 3. 在探测面追迹光线 C CX\"-C 4. 在探测面计算照度 Cl]E rg 5. 使用PutWorkspaceData发送照度数据到Matlab u|\Lb2Kb: 6. 使用PutFullMatrix发送标量场数据到Matlab中 ,k/*f+t 7. 用Matlab画出照度数据 EpeTfD 8. 在Matlab计算照度平均值 j]6j!.1 9. 返回数据到FRED中 pd,5 .d R\+p`n $ 代码分享： Hq^ sU% U ]fE(mpI9 Option Explicit rZZueYuXO a[)i n ,3 Sub Main v\t$. _at 3a_S-&?X Dim ana As T_ANALYSIS `jJ5us Dim move As T_OPERATION _ 9Tv* @ Dim Matlab As MLApp.MLApp q[l},nw Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long U\y];\~ H Dim raysUsed As Long, nXpx As Long, nYpx As Long VZJs@q x:Z Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double 8|?$KLz?F> Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double zHr1FxD Dim meanVal As Variant l.lXto.6) u
