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。 PBgU/zVn Ym
1; /' 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: URj2 evYW enableservice('AutomationServer', true) uuYeXI; enableservice('AutomationServer') -(9TM*)O l]S% k& 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。 Wx|De7* b&*N 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: o`{^ptu1q 1. 在FRED脚本编辑界面找到参考. !H~PF*,hY 2. 找到Matlab Automation Server Type Library UHX,s 3. 将名字改为MLAPP ?P(U/DS8 ~$m:j]; z~#d@c\ 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。 ;jFUtG }B&+KO) 图 编辑/参考 .yQ< <STE~ZmO 现在将脚本代码公布如下,此脚本执行如下几个步骤: nT=XWM 1. 创建Matlab服务器。 S.!K 2. 移动探测面对于前一聚焦面的位置。 =J'&.@Dwz 3. 在探测面追迹光线 ,y gDNF 4. 在探测面计算照度 [I78<IJc 5. 使用PutWorkspaceData发送照度数据到Matlab @P<aTRy,f 6. 使用PutFullMatrix发送标量场数据到Matlab中 .GIygU_ 7. 用Matlab画出照度数据 -V=,x3Zew 8. 在Matlab计算照度平均值 o>A']+`Eu 9. 返回数据到FRED中 vPD%5AJN 4VHX4A}CgA 代码分享: qq>Qi (> ;:'A Bfs Option Explicit H6<3'P [E9)Da_)i Sub Main JdX!#\O E51S#T Dim ana As T_ANALYSIS oW3Uyj Dim move As T_OPERATION k\A4sj Dim Matlab As MLApp.MLApp 4{LKT^(!f Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long o&Y
