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。 G8oOFBQD cw{[% 7 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: :<Y, f(c enableservice('AutomationServer', true) m-No 8)2yA enableservice('AutomationServer') "# mr?h_ [Y]\sF;J 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。 x+7jJ=F '|i<?]U 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: +V6N/{^5 1. 在FRED脚本编辑界面找到参考. _/5mgn<GK 2. 找到Matlab Automation Server Type Library /A;!g5Y 3. 将名字改为MLAPP d^WEfH miZ&9m 'Nv*ePz 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。 %<w)#eV? *:3`$`\54 图 编辑/参考 `8%2F}x}qD n089tt=TE 现在将脚本代码公布如下,此脚本执行如下几个步骤: A/EW57v" 1. 创建Matlab服务器。 1x#Z}XG 2. 移动探测面对于前一聚焦面的位置。 jn9KQe\3 3. 在探测面追迹光线 {1V~`1(w 4. 在探测面计算照度 -HU5E>xG 5. 使用PutWorkspaceData发送照度数据到Matlab KfsU RTZ 6. 使用PutFullMatrix发送标量场数据到Matlab中 #;6YADk2_ 7. 用Matlab画出照度数据 =FXZcP>h 8. 在Matlab计算照度平均值 wh@;$s"B 9. 返回数据到FRED中 C&m[/PJ~l 195m0'zda 代码分享: gzthM8A L}1|R*b Option Explicit ;|f|d?Q\ j\D_Z{m2 Sub Main *94<rlh{"
