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。 ({"jL*S,q %OI4}!z@l 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: my.%zF enableservice('AutomationServer', true) x]e&G!| enableservice('AutomationServer') rA=iBb3` oS2L"# 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。 vlygS(Y_7 E%B:6 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: e`N /3q7 1. 在FRED脚本编辑界面找到参考. rc_K|Df 2. 找到Matlab Automation Server Type Library 8ZnHp~ 3. 将名字改为MLAPP i!|OFU6 y4jJ& m1d*Lt>F@ 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。 HDV@d^]- +7`7cOqXg 图 编辑/参考 _m;H$N~I# #i t) 现在将脚本代码公布如下,此脚本执行如下几个步骤: .B9i`)0 1. 创建Matlab服务器。 L0sb[:'luz 2. 移动探测面对于前一聚焦面的位置。 q6A"+w,N 3. 在探测面追迹光线 Rxl )[\A* 4. 在探测面计算照度 *$+:Cbe-F 5. 使用PutWorkspaceData发送照度数据到Matlab )BJ Z{E* 6. 使用PutFullMatrix发送标量场数据到Matlab中 []\=(Uc; 7. 用Matlab画出照度数据 Vo G`@^s 8. 在Matlab计算照度平均值 M5C%(sQ$ 9. 返回数据到FRED中 4!l%@R>O2 Hzn6H4Rc 代码分享: EG7.FjnVu @(b;H0r~ Option Explicit acPX2B[jJ AA&5wDMV> Sub Main =!V-V}KK- E1"H(m&6 Dim ana As T_ANALYSIS PQ}owEJ2eM Dim move As T_OPERATION F\)?Ntj)>@ Dim Matlab As MLApp.MLApp lD K<gd Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long 9i8 ~ Dim raysUsed As Long, nXpx As Long, nYpx As Long \DgWp:| Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double (E*pM$ Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double t,v=~LE Dim meanVal As Variant /:BM]K o 9?#;B$ Set Matlab = CreateObject("Matlab.Application") R9-Ps qmF 40M/Gu: ClearOutputWindow gO9\pI2 s|q]11r+H 'Find the node numbers for the entities being used. ~T'!.^/ detNode = FindFullName("Geometry.Screen") D.ajO^[ detSurfNode = FindFullName("Geometry.Screen.Surf 1") @pn<x"F5' anaSurfNode = FindFullName("Analysis Surface(s).Analysis 1") 9 M<3m u?a4v \ 'Load the properties of the analysis surface being used.
