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。 G[z
.&l BD*G1k_q 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: 2\@Z5m3B enableservice('AutomationServer', true) M-MKk:o enableservice('AutomationServer') Qv{,wytyO QLr9dnA 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。 srmKaa| {fz$Z!8- 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: dM]#WBOPy 1. 在FRED脚本编辑界面找到参考. aj8Rb& 2. 找到Matlab Automation Server Type Library 0k[2jh 3. 将名字改为MLAPP EHI 'xt nk@atK,38^ J YmAn?o- 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 o"q+,"QL p'Bm8=AwD 图 编辑/参考 q7Es$zjX xJhU<q~? 现在将脚本代码公布如下,此脚本执行如下几个步骤: wCb(>pL0 1. 创建Matlab服务器。 yyP-=Lhmo= 2. 移动探测面对于前一聚焦面的位置。 ^jyD# 3. 在探测面追迹光线 ;=~Xr"(/z 4. 在探测面计算照度 ?F@%S3h. 5. 使用PutWorkspaceData发送照度数据到Matlab YpmYxd^ 6. 使用PutFullMatrix发送标量场数据到Matlab中 6"QEJ 7. 用Matlab画出照度数据 pIO4,VL;W 8. 在Matlab计算照度平均值 A
