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\_4C  
B<oBo&uA  
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: HMqR%A  
enableservice('AutomationServer', true) +~f=L- >  
enableservice('AutomationServer') <P.'r,"[  
G- eSHv  
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。 MZ"|Jn  
,v_NrX=f?  
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: M3Oqto<8"  
1. 在FRED脚本编辑界面找到参考. ch]{ =61  
2. 找到Matlab Automation Server Type Library Cxra(!&  
3. 将名字改为MLAPP |(3"_  
uS7kkzt-x  
yoG*c%3V?  
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。 x4-_K%

现在将脚本代码公布如下,此脚本执行如下几个步骤: .JX9(#Uk  
1. 创建Matlab服务器。 FA!!S`{\  
2. 移动探测面对于前一聚焦面的位置。 tR(nD UHV5  
3. 在探测面追迹光线 ~DP_1V?  
4. 在探测面计算照度 vW4n>h}]  
5. 使用PutWorkspaceData发送照度数据到Matlab KvXF zx|A  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ZaF9Q%  
7. 用Matlab画出照度数据 R*DQLBWc  
8. 在Matlab计算照度平均值 hGJANA  
9. 返回数据到FRED中 .FC|~Z1T<F
