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。 !pkIaCxs ?Zsh\^k.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: ~P"Agpx3u enableservice('AutomationServer', true) {$i>\) enableservice('AutomationServer') 0:<Y@#L W&&|T;P<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。 [u37Hy_Gi ~G-W|> 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: TA2ETvz^ 1. 在FRED脚本编辑界面找到参考. 4y?n62N8$ 2. 找到Matlab Automation Server Type Library ~!Nw]lb! 3. 将名字改为MLAPP Xo]2iQy S' kgpF"bm ?6hd(^ 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。 YD;d*E%t 0a^bAEP 图 编辑/参考 vy{k"W&S wfpl]d! 现在将脚本代码公布如下,此脚本执行如下几个步骤: `JpFqZ'58 1. 创建Matlab服务器。 ey,f igjd. 2. 移动探测面对于前一聚焦面的位置。 ,UNk]vd 3. 在探测面追迹光线 -2 >s#/% 4. 在探测面计算照度 EP>Lh7E9n 5. 使用PutWorkspaceData发送照度数据到Matlab gx',K1T 6. 使用PutFullMatrix发送标量场数据到Matlab中 32?'jRN(ue 7. 用Matlab画出照度数据 $eG_LY 1v 8. 在Matlab计算照度平均值 :]]x^wony~ 9. 返回数据到FRED中 l|E4 7@# FI.F6d)E$ 代码分享: ~ {yy{ L jTSu9I> Option Explicit NN1}P'6Ha J:gC1g^ Sub Main _SOwiz #+V4<o Dim ana As T_ANALYSIS 9H/R@i[E Dim move As T_OPERATION |iX>hJSl Dim Matlab As MLApp.MLApp dcD#!v\0 Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long [ }Tb2| Dim raysUsed As Long, nXpx As Long, nYpx As Long doHE]gC2Uz Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double sxph#E% Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double KK2YT/K$SG Dim meanVal As Variant -]Su+/3(, JGTsVa2 Set Matlab = CreateObject("Matlab.Application") {wj%WSQj/y <tZZ]Y] ClearOutputWindow DB-79U %W $fT5Vc]B4 'Find the node numbers for the entities being used. -3v\ c~ detNode = FindFullName("Geometry.Screen") l9="ccM detSurfNode = FindFullName("Geometry.Screen.Surf 1") #jG?{j3;? anaSurfNode = FindFullName("Analysis Surface(s).Analysis 1") v;9(FLtL ;-@: }/ 'Load the properties of the analysis surface being used. o:W*#dt LoadAnalysis anaSurfNode, ana njg0MZBqA WysWg7,r 'Move the detector custom element to the desired z position.
