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。 LY-2sa#B$- Is+O 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: zRPeNdX enableservice('AutomationServer', true)
1!>Jpi0 enableservice('AutomationServer') sN5B7)Vc |g*XK6 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 =Fdg/X1 puT'y 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: %Z*sU/^ 1. 在FRED脚本编辑界面找到参考. ;t+ub8 2. 找到Matlab Automation Server Type Library Afk$?wkL 3. 将名字改为MLAPP m>SErxU(z |.wEm;Bz B 2ec@]uD` 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。 xZV1k~C VWO9=A*Y| 图 编辑/参考 VcoOeAKL ;V<fB/S.=+ 现在将脚本代码公布如下,此脚本执行如下几个步骤: cYqfsd# B 1. 创建Matlab服务器。 _/O25% l 2. 移动探测面对于前一聚焦面的位置。 W2.qhY 5 3. 在探测面追迹光线 /@|/^vld 4. 在探测面计算照度 a+Ac[> 5. 使用PutWorkspaceData发送照度数据到Matlab S%`0'lzzj 6. 使用PutFullMatrix发送标量场数据到Matlab中 (64yg 7. 用Matlab画出照度数据 rl0< Ls 8. 在Matlab计算照度平均值 B,{K*-7)MX 9. 返回数据到FRED中 -I=l8m6L JY6
