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。 i.7_ i78\" n.a2%,|v 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: zSD_t enableservice('AutomationServer', true) %z1^ enableservice('AutomationServer') xRgdU+,Mj `pCy:J?d>l 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。 [jlum>K 0wNlt#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: hKN ;tq, 1. 在FRED脚本编辑界面找到参考. bo90;7EK8 2. 找到Matlab Automation Server Type Library @iV-pJ- 3. 将名字改为MLAPP GRYw_}Aa zI,Qc60B et~D9='E 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。 60{DR >S <`=Kt[_BQ 图 编辑/参考 r ~UDK]?V ogQfzk 现在将脚本代码公布如下,此脚本执行如下几个步骤: .TdFI"Yn 1. 创建Matlab服务器。 e21J9e6z 2. 移动探测面对于前一聚焦面的位置。 \ +sa[jK 3. 在探测面追迹光线 hx;kNcPbI 4. 在探测面计算照度 ;Wy03}K4J 5. 使用PutWorkspaceData发送照度数据到Matlab bri8o" 6. 使用PutFullMatrix发送标量场数据到Matlab中 3{~(_ 7. 用Matlab画出照度数据 <EgJm`V 8. 在Matlab计算照度平均值 7- LjBlH 9. 返回数据到FRED中 fU
