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。 [hSJ)IZh {Vj&i.2, 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: W]/J]O6 enableservice('AutomationServer', true) i[9yu- enableservice('AutomationServer') jUM'f24 F}{%*EJ 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。 ]}lt^7\= N$kxf 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 1s(T#jh 1. 在FRED脚本编辑界面找到参考. ,2$<Pt; 2. 找到Matlab Automation Server Type Library 'UhHcMh: 3. 将名字改为MLAPP QNOdt 2NN .x%w# i*/i"W< 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。 1v|-+p42 0&sa#g2 图 编辑/参考 2|^@=.4\ JWd[zJ[ 现在将脚本代码公布如下,此脚本执行如下几个步骤: u ,3B[ 1. 创建Matlab服务器。 OM0r*<D"! 2. 移动探测面对于前一聚焦面的位置。 Lq5xp< 3. 在探测面追迹光线 (a#gCG\ 4. 在探测面计算照度 OJpfiZ@Q_ 5. 使用PutWorkspaceData发送照度数据到Matlab :wS&3:h 6. 使用PutFullMatrix发送标量场数据到Matlab中 %4m Nk}tyH 7. 用Matlab画出照度数据 ]uox ^HC 8. 在Matlab计算照度平均值 vcdVck@ 9. 返回数据到FRED中 0]bt}rh qZ^
