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。 \Oa11c`6 `5t
CmU 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: M7\K iQd enableservice('AutomationServer', true) RVa{% enableservice('AutomationServer') S(hT3MAW #e$vv!&} 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。 0J1&6b 78FK{Cr 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: :.W</o~\s 1. 在FRED脚本编辑界面找到参考. kr5'a:F) 2. 找到Matlab Automation Server Type Library UJrN+RtL 3. 将名字改为MLAPP =_,j89E g42Z*+P6N hE}y/A[ 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。 z]=jer ^%m~V LH 图 编辑/参考 5t[7taLX\ k3r<']S^ 现在将脚本代码公布如下,此脚本执行如下几个步骤: -^= JKd&p 1. 创建Matlab服务器。 <|4L+?_(& 2. 移动探测面对于前一聚焦面的位置。 `Bv, :i 3. 在探测面追迹光线 %51HJB}C] 4. 在探测面计算照度 8DZ
