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。 ET:B" 6d%'>^`(o- 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: C?h`i ^ >2 enableservice('AutomationServer', true) +i1\],7 enableservice('AutomationServer') P3u,)P& 1}>u Y 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。 _WeN\F~^ " +n\0j; 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: !5escR!\D 1. 在FRED脚本编辑界面找到参考. \8HLQly|@ 2. 找到Matlab Automation Server Type Library SeX:A)*ez% 3. 将名字改为MLAPP ;xMieqz {%cm;o[7o JAA{5@ST 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。 Qk_`IlSd @w]z"UCwV@ 图 编辑/参考 Dw-i!dq 8/16<yZ 现在将脚本代码公布如下,此脚本执行如下几个步骤: !v`C-1}70 1. 创建Matlab服务器。 V {H/>>k7 2. 移动探测面对于前一聚焦面的位置。 Mq[|w2. 3. 在探测面追迹光线 jh3XG 4. 在探测面计算照度 7x ?2(( 5. 使用PutWorkspaceData发送照度数据到Matlab ulzQ[?OMl 6. 使用PutFullMatrix发送标量场数据到Matlab中 *k%3J9=-1 7. 用Matlab画出照度数据 M(+;AS?; 8. 在Matlab计算照度平均值 IQ3]fLb 9. 返回数据到FRED中 MG6y ))z1T 8 代码分享: IX]K"hT y7x[noGtR Option Explicit #vnJJ#uI|> 2-#:Y
