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。 nrA}36 E 5RTAM 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: a'Qy]P}'Ug enableservice('AutomationServer', true) ?S0VtHQ enableservice('AutomationServer') a7q-*%+d5 Xig+[2zS 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。 ,KIa+&vJW@ )j@k[}R#g 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: x-U^U.i@ 1. 在FRED脚本编辑界面找到参考. xN}P0 2. 找到Matlab Automation Server Type Library &^4W+I{H 3. 将名字改为MLAPP |zvxKIW;wd ^?toTU }x-~>$:" 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 KL0u:I(lWU >lyUr*4PX 图 编辑/参考 FWdSpaas Q (J<@e!@NE 现在将脚本代码公布如下,此脚本执行如下几个步骤: &.o}(e:] 1. 创建Matlab服务器。 n\*>mp) 2. 移动探测面对于前一聚焦面的位置。 G+'MTC_ 3. 在探测面追迹光线 GwwxSB&y 4. 在探测面计算照度 ygUvO3Z 5. 使用PutWorkspaceData发送照度数据到Matlab 4^alAq^ 6. 使用PutFullMatrix发送标量场数据到Matlab中 ^$_ifkkLz 7. 用Matlab画出照度数据 pLBp[GQ 8. 在Matlab计算照度平均值 '4FS.0*_ 9. 返回数据到FRED中 $z{HNY*2 _QBd3B% 代码分享: ;myu8B7& BaiC;&(
