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。 !D6]JPX *p d@.|^)m 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: \vNU,WO enableservice('AutomationServer', true) AA_%<zK enableservice('AutomationServer') <@}9Bid!o bt *k.=p 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。 N`i/mP nN;u,}e 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: =N@t'fOr 1. 在FRED脚本编辑界面找到参考. ~[: 2I 2. 找到Matlab Automation Server Type Library yZ:qU({KhD 3. 将名字改为MLAPP =Qq+4F)MD rQX zR U*:!W=XN 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。 :&Nbw 8L XHk l 图 编辑/参考 58K5ZZG E^PB)D(. 现在将脚本代码公布如下,此脚本执行如下几个步骤: a.'*G6~Qgw 1. 创建Matlab服务器。 )0MB9RMk1 2. 移动探测面对于前一聚焦面的位置。 0x7'^Z>-oe 3. 在探测面追迹光线 $e\M_hp*J 4. 在探测面计算照度 q4q6c")zp 5. 使用PutWorkspaceData发送照度数据到Matlab SuznN
