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。 [ C d"@!yA ?z0f5<dL 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: B;tU+36nM enableservice('AutomationServer', true) |,M&ks enableservice('AutomationServer') 3;=nQ{0b h+F@apUS 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。 ;;'b;,/ 9i@AOU 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: CBdSgHA3> 1. 在FRED脚本编辑界面找到参考. tdg.vYMDPC 2. 找到Matlab Automation Server Type Library s>z$_ 3. 将名字改为MLAPP epa)ctS9 3N6U6.Tqb k7P~*ll$ 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。 d{+H|$L` :0>wm@qCQ 图 编辑/参考 )3v0ex@Jl mLX1w)=r 现在将脚本代码公布如下,此脚本执行如下几个步骤: pv039~Sud 1. 创建Matlab服务器。 AfW63;kH 2. 移动探测面对于前一聚焦面的位置。 Gxfw!aF~ 3. 在探测面追迹光线 )k0e} 4. 在探测面计算照度 I!lzOg4~ 5. 使用PutWorkspaceData发送照度数据到Matlab ?^P#P0 6. 使用PutFullMatrix发送标量场数据到Matlab中 ~(Gv/x 7. 用Matlab画出照度数据 cAC2Xq 8. 在Matlab计算照度平均值 Pi::cf>3 9. 返回数据到FRED中 NWPL18*C Nk=F.fp|/ 代码分享: _H^Ij H4 Y7p Option Explicit m>2b %GTh 0$l=ME( Sub Main YXXUYi~!f p%Ae"#_X% Dim ana As T_ANALYSIS e3YZ-w^W~h Dim move As T_OPERATION OO_{o Dim Matlab As MLApp.MLApp =BY)>0?z Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long =:`1!W0I Dim raysUsed As Long, nXpx As Long, nYpx As Long pVn6>\xa Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double JbzYr]k Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double -yfyd$5j Dim meanVal As Variant ==(9P`\ xtf]U:c Set Matlab = CreateObject("Matlab.Application") iQ*JU2;7t 0TU~Q ClearOutputWindow {y<[1Pms l)D18 'Find the node numbers for the entities being used. )/2* <jr detNode = FindFullName("Geometry.Screen") w<j6ln+nM detSurfNode = FindFullName("Geometry.Screen.Surf 1") VuFMjY anaSurfNode = FindFullName("Analysis Surface(s).Analysis 1") &5/`6-K DU$]e1 'Load the properties of the analysis surface being used. &J^@TgqL^ LoadAnalysis anaSurfNode, ana '[JrP<~^o ,0[8/)$M 'Move the detector custom element to the desired z position. cRz7.9-< z = 50 isHa4 D0 GetOperation detNode,1,move mB;W9[ move.Type = "Shift" =Y|TShKk move.val3 = z AQ.
