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。 mLm?yb: "Tz'j}< 9C 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: `Vl9/IEk enableservice('AutomationServer', true) 1V.oR`&2E enableservice('AutomationServer') R9\ )a2 <NWq03:& 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。 A~}5T%qb 'e/wjV 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: LS]0 p# 1. 在FRED脚本编辑界面找到参考. %z~=Jz^ 2. 找到Matlab Automation Server Type Library QtQbr*q@% 3. 将名字改为MLAPP Z5|BwM Z0%:j\W4c V:h7}T95 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。 LyH1tF Jb*E6-9G 图 编辑/参考 )M><09 gCq'#G\Z 现在将脚本代码公布如下,此脚本执行如下几个步骤: D$N;Qb 1. 创建Matlab服务器。 =;"=o5g_ 2. 移动探测面对于前一聚焦面的位置。 V]NCFG 3. 在探测面追迹光线 Z C<+BKS 4. 在探测面计算照度 $C{,`{= 5. 使用PutWorkspaceData发送照度数据到Matlab < 1[K1'7h 6. 使用PutFullMatrix发送标量场数据到Matlab中 g%<n9AUl 7. 用Matlab画出照度数据 |'-%d^Z 8. 在Matlab计算照度平均值 CEW1T_1U<\ 9. 返回数据到FRED中 u4j"U6"]M _\na9T~g 代码分享: X,{ 3_ S$ffTdRz Option Explicit 2Qt!JXC yd=b!\}WJ Sub Main ocu,qL)W b~qH/A}h Dim ana As T_ANALYSIS "T9UedZ Dim move As T_OPERATION kH8/8 Dim Matlab As MLApp.MLApp .,20_<j%= Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long k!Q{u2 Dim raysUsed As Long, nXpx As Long, nYpx As Long @VPmr}p:{ Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double Q(36RX%@ Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double Wy%FF\D.Y Dim meanVal As Variant Z&O6<=bg!
