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。 qZ X/@Yxz }V`mp 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: YRcps0Dx9 enableservice('AutomationServer', true) 8C7Z{@A enableservice('AutomationServer') s9j7Psd *>."V5{;S 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。 zoZH[a`H UtJ a3ya 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: L1#Ij# 1. 在FRED脚本编辑界面找到参考. 9[Qd)%MO 2. 找到Matlab Automation Server Type Library rU2iy"L 3. 将名字改为MLAPP nE|@IGH ^gYD*K!* Cifd21v4 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。 ?c#$dc" z`U Ukl}T 图 编辑/参考 -iN.Iuc{b_ Q@QFV~ 现在将脚本代码公布如下,此脚本执行如下几个步骤: N1x@-/xa| 1. 创建Matlab服务器。 lMifpK 2. 移动探测面对于前一聚焦面的位置。 `<fh+* 3. 在探测面追迹光线 <@uOCRbV 4. 在探测面计算照度 DQXS$uBT 5. 使用PutWorkspaceData发送照度数据到Matlab PQ U]l"A 6. 使用PutFullMatrix发送标量场数据到Matlab中 ux-CpI 7. 用Matlab画出照度数据 uT_!'l$fr 8. 在Matlab计算照度平均值 80B>L 9. 返回数据到FRED中 :`Az/U[ R,_d1^|*w 代码分享: rg QEUDEQ hOk00az Option Explicit m{%t?w$Au )TmtSSS Sub Main =A!S/;z> z/]q)`G Dim ana As T_ANALYSIS pa<qZZ Dim move As T_OPERATION & >JDPB?5 Dim Matlab As MLApp.MLApp #exss=as/ Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long H+C6[W= Dim raysUsed As Long, nXpx As Long, nYpx As Long 7^:4A' Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double m7qqY
