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。 T^Y([23 OjFLPGRCh 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: 4[.oPK=i enableservice('AutomationServer', true) <D:.(AUeO enableservice('AutomationServer') 1M}5>V{ V,mw[Hw 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。 ur3(HL '9S8}q 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: 7Nk!1s: 1. 在FRED脚本编辑界面找到参考. u -;_y='m 2. 找到Matlab Automation Server Type Library Q~OxH'>>( 3. 将名字改为MLAPP Jbjmv:db T+*%?2>q" Q?nN!eT 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。 ->l%TCHP 8kU!8^mH 图 编辑/参考 )CuZDf@ N"" BCh" 现在将脚本代码公布如下,此脚本执行如下几个步骤: CS@FYO 1. 创建Matlab服务器。 -&3hEv5 2. 移动探测面对于前一聚焦面的位置。 mzeY%A<0^ 3. 在探测面追迹光线 ;LG#.~f 4. 在探测面计算照度 /JHc!
