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。 :~p_(rE }dSFv
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:
c70B enableservice('AutomationServer', true) E8o9ufj3 enableservice('AutomationServer') &A^2hPe} xG(:O@ 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。 cSj(u%9} FYK}AR<= 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: XV!UeBq 1. 在FRED脚本编辑界面找到参考. :0Fwaw9PH" 2. 找到Matlab Automation Server Type Library )EG-xo@X 3. 将名字改为MLAPP ik0w\* :$QwOz^N* *}LQZFrnX 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 QEEX|WM 7RgnL<t~:8 图 编辑/参考 S1!_ IK$m l`];CALA4 现在将脚本代码公布如下,此脚本执行如下几个步骤: 3iiOxg?j 1. 创建Matlab服务器。 ezd@>(hJ 2. 移动探测面对于前一聚焦面的位置。 lqKwjJtX 3. 在探测面追迹光线 cr{dl\Na 4. 在探测面计算照度 ;~s@_}& 5. 使用PutWorkspaceData发送照度数据到Matlab *1}vn%wvn 6. 使用PutFullMatrix发送标量场数据到Matlab中 !" : arK 7. 用Matlab画出照度数据 6:\z8fYD 8. 在Matlab计算照度平均值 W*D*\E 9. 返回数据到FRED中 t*Wxvoxk ,-BZsZ0~ 代码分享: a[gN+DX%L OL[_2m*;9p Option Explicit 1 z[blNs& >2)!w Sub Main I3?:KVa ~0 n9In% Dim ana As T_ANALYSIS {XYf"ONi Dim move As T_OPERATION Vs[!WJ
