FRED如何调用Matlab

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。 T[?wbYfW  
JD\yl[ac%  
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: ?"hrCEHV{9  
enableservice('AutomationServer', true) 3VI[*b  
enableservice('AutomationServer') `EBI$;!  
yT$CImP73  
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。 ]VKM3[

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: XY_hTHJ  
1. 在FRED脚本编辑界面找到参考. Q>ZxJ!B<k  
2. 找到Matlab Automation Server Type Library |2L|Zp&  
3. 将名字改为MLAPP j ."L=  
~nP~6Q'wSH  
W?>C$_p C  
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。 k?bIu

现在将脚本代码公布如下,此脚本执行如下几个步骤: nE&`~  
1. 创建Matlab服务器。 6D\$K  
2. 移动探测面对于前一聚焦面的位置。 dCb7sqJ%  
3. 在探测面追迹光线 X[SdDYMY  
4. 在探测面计算照度 U}yq*$N  
5. 使用PutWorkspaceData发送照度数据到Matlab ~cf*Oq  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ]\JLlQ}#H  
7. 用Matlab画出照度数据 2@Nt6r  
8. 在Matlab计算照度平均值 $q|-9B  
9. 返回数据到FRED中 2iWS k6%R
