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。 *V"cu ^c(PZ,/#JB 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: R<U?)8g,h~ enableservice('AutomationServer', true) zA"D0fr enableservice('AutomationServer') /p%K[)T( NI^Y%N 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。 $&e(V6A@ =V,'f 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: PZ ogN 1. 在FRED脚本编辑界面找到参考. mJsYY,b8 2. 找到Matlab Automation Server Type Library 6=@n
b3D% 3. 将名字改为MLAPP y1
}d(% pz$$K? s?6 7@\ 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。 VmUM_Q~ !gk\h 图 编辑/参考 #/tdZ0 |@@mq!>- 现在将脚本代码公布如下,此脚本执行如下几个步骤: Z956S$gS 1. 创建Matlab服务器。 "=".ne 2. 移动探测面对于前一聚焦面的位置。 5~44R@` 3. 在探测面追迹光线 _L=vK=, 4. 在探测面计算照度 W?l .QQk 5. 使用PutWorkspaceData发送照度数据到Matlab U1"t|KW8 6. 使用PutFullMatrix发送标量场数据到Matlab中 ROjjN W`W 7. 用Matlab画出照度数据 zgRP!q<9tt 8. 在Matlab计算照度平均值 *g,?13Q_ 9. 返回数据到FRED中 kK1qFe?] ~NcJLU!au 代码分享: (jm.vL&5j Z~,.l
