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。 6oa>\PDy ,)uW`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: Wks zNh enableservice('AutomationServer', true) IL:[0q enableservice('AutomationServer') YZ]}l%e $EHFf$M 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。 ])G|U A. 9_?<T;]" 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: /Xj{]i3{ 1. 在FRED脚本编辑界面找到参考. 5t-d+vB 2. 找到Matlab Automation Server Type Library C?k\5AzT 3. 将名字改为MLAPP _xH<R \[qxOZ{ #eN2{G=4+ 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。 s Pb}A$' W}N7jPO} 图 编辑/参考 k]C k%[d -+u}u=z% 现在将脚本代码公布如下,此脚本执行如下几个步骤: VxS3lR= 1. 创建Matlab服务器。 Z"'*A\r2 2. 移动探测面对于前一聚焦面的位置。 FZ}^)u}o 3. 在探测面追迹光线 Yyar{$he 4. 在探测面计算照度 `#w#!@s#@ 5. 使用PutWorkspaceData发送照度数据到Matlab *59| 6. 使用PutFullMatrix发送标量场数据到Matlab中 r~JGs?GH 7. 用Matlab画出照度数据 9BpxbU+L; 8. 在Matlab计算照度平均值 '^C
