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。 eN*=wOh ZUDdLJ 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: LW+a-i enableservice('AutomationServer', true) U5rcI6 enableservice('AutomationServer') )-2sk@y -)cau-(X 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。 QU`M5{# cvoE4&m! 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: uJBs 3X 1. 在FRED脚本编辑界面找到参考. !m7`E 2. 找到Matlab Automation Server Type Library d4y?2p ?3 3. 将名字改为MLAPP x2-i1#j`; @|e4.(9A X5s.F%Np! 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。 +ZuT\P&kR5 \0}!qG![AA 图 编辑/参考 /(/Z~J[ 4!%@{H`3 现在将脚本代码公布如下,此脚本执行如下几个步骤: j@yK#==k 1. 创建Matlab服务器。 JnC$}amr 2. 移动探测面对于前一聚焦面的位置。 6Z5X?B 3. 在探测面追迹光线 1iS]n;xcl/ 4. 在探测面计算照度 G~$.Af!9W 5. 使用PutWorkspaceData发送照度数据到Matlab Y|'0bujr 6. 使用PutFullMatrix发送标量场数据到Matlab中 ll]MBq 7. 用Matlab画出照度数据 0F"W~OQ6 8. 在Matlab计算照度平均值 (lNV\Za 9. 返回数据到FRED中 hDO\Q7 ,r=9$i_ 代码分享: _J|TCm li!3bv Option Explicit [r[IWy(} & XS2q0-x Sub Main =r w60B Qs38VlR_m Dim ana As T_ANALYSIS h8nJt>h Dim move As T_OPERATION 0_!')+ Dim Matlab As MLApp.MLApp K-_XdJ\ Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long vbo|q[z Dim raysUsed As Long, nXpx As Long, nYpx As Long 8R3x74fL Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double x.5!F2$ Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double [uJfmr EH Dim meanVal As Variant 8OS@gpz J$aE:g6' Set Matlab = CreateObject("Matlab.Application") >i6sJ)2?> fX
