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。 (Cqhk:F F9-xp7T 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: ~H)b vN^ enableservice('AutomationServer', true) M2vYOg`t:c enableservice('AutomationServer') v:s~Y A4 o'EQ?~ 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。 5BTQJa mi<V(M~p 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: ]?b#~ 1. 在FRED脚本编辑界面找到参考. 0j_`7<,: 2. 找到Matlab Automation Server Type Library oy#Qj3M8= 3. 将名字改为MLAPP 0alm/or dJ:EXVU dhsQfWg#} 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。 ~qco -b krI<'m;a 图 编辑/参考 d,+d8X K`PF|=z 现在将脚本代码公布如下,此脚本执行如下几个步骤: ?5jkb 1. 创建Matlab服务器。 n\wO[l) 2. 移动探测面对于前一聚焦面的位置。 h]vA%VuE'E 3. 在探测面追迹光线 tE=P9 \4 4. 在探测面计算照度 5?%(j!p5 5. 使用PutWorkspaceData发送照度数据到Matlab v#nYH?+~mJ 6. 使用PutFullMatrix发送标量场数据到Matlab中 E3;[*ve 7. 用Matlab画出照度数据 ~.yt 8. 在Matlab计算照度平均值 +hV7o!WxC 9. 返回数据到FRED中 MU%C_d%. \ec,=7S<Zf 代码分享: Th'6z#h:U &37QUdp+p Option Explicit ![{> f6{J %R-"5?eTtu Sub Main |*i0h`a .K XpB7: Dim ana As T_ANALYSIS Jc(tV(z Dim move As T_OPERATION -:AknQq Dim Matlab As MLApp.MLApp 50Pz+: Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long !imm17XQ\ Dim raysUsed As Long, nXpx As Long, nYpx As Long *:aJlvk Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double '@ (WT~g Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double AEe*A+ Dim meanVal As Variant ]k
