[分享]FRED如何调用Matlab [复制链接]

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。 2"T8^r|U  
}U2[?  
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： iP~sft6  
enableservice('AutomationServer', true) I?f"<5[0  
enableservice('AutomationServer') 1zdYBb6;j  
`^O'V}T  
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。 rDpe_varA

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： cj$,ob&DX  
1. 在FRED脚本编辑界面找到参考. }R`8h&J  
2. 找到Matlab Automation Server Type Library b cC\  
3. 将名字改为MLAPP "AT&!t[J

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。 |!$ Q<-]f

现在将脚本代码公布如下，此脚本执行如下几个步骤： WEno+Z~=1'  
1. 创建Matlab服务器。 TAXd,z N  
2. 移动探测面对于前一聚焦面的位置。 60~v t04  
3. 在探测面追迹光线 uEBQo
P2  
4. 在探测面计算照度 2}D,df'W4  
5. 使用PutWorkspaceData发送照度数据到Matlab [vE$R@TZ0!  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Xfj)gPt}  
7. 用Matlab画出照度数据 7^c2e*S  
8. 在Matlab计算照度平均值 g+:$X- r  
9. 返回数据到FRED中 J09*v)L
