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。 )?anOD[ n"c[,k+R`U 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:
;{N!Eb`S enableservice('AutomationServer', true) U2W|:~KM enableservice('AutomationServer') C&(N
I |IzPgC 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。 ;@oN s- Li4zTR|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: #cI{Fe0h 1. 在FRED脚本编辑界面找到参考. #V~me 2. 找到Matlab Automation Server Type Library 0Qf,@^zL* 3. 将名字改为MLAPP s Z].8. (@fHl=! Za V Y7[) 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。 I 7{T Pd_U7&w,5 图 编辑/参考 [1Qo#w1 ivJ@=pd)B 现在将脚本代码公布如下,此脚本执行如下几个步骤: SE1=>S%p 1. 创建Matlab服务器。 qm/22:&v5 2. 移动探测面对于前一聚焦面的位置。 <h0?tv] 3. 在探测面追迹光线 | ATvS2 4. 在探测面计算照度 &w_j/nW^' 5. 使用PutWorkspaceData发送照度数据到Matlab g}1B;zGf 6. 使用PutFullMatrix发送标量场数据到Matlab中 2K/4Rf0; 7. 用Matlab画出照度数据 .YAT:;L 8. 在Matlab计算照度平均值
