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。 yGvBQ2kYb fRomP-S 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: |}isSCt enableservice('AutomationServer', true) }}u16x}*n enableservice('AutomationServer') p&k%d, * \/F*JPhy 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。 Czb:nyRj Mew,g:m: 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: yyM`J7]J 1. 在FRED脚本编辑界面找到参考. {wvBs87 2. 找到Matlab Automation Server Type Library JiFB<Q\ 3. 将名字改为MLAPP ^5rB/y, EHk$,bM 2U@:.S'K 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。 Q)2i{\GPVn a[@Y> 图 编辑/参考 (CInt_dBw~ QzVo U | 现在将脚本代码公布如下,此脚本执行如下几个步骤: iaHL&)[YK 1. 创建Matlab服务器。 p9![8VU 2. 移动探测面对于前一聚焦面的位置。 3@wio[ 3. 在探测面追迹光线 /z`.- D( 4. 在探测面计算照度 O'h f8w 5. 使用PutWorkspaceData发送照度数据到Matlab xq&r|el 6. 使用PutFullMatrix发送标量场数据到Matlab中 Q#zU0K*^ 7. 用Matlab画出照度数据 Af Y]i 8. 在Matlab计算照度平均值 W0XfU` 9. 返回数据到FRED中 1xjWD30 jx14/E+^ 代码分享: .~X&BY>qP 6k`O Option Explicit ^j7>Ul,
