[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。 E6ElNgL  
mxC;?s;~  
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： /nNN,hz  
enableservice('AutomationServer', true) f}f9@>.  
enableservice('AutomationServer') #OD/$f_  
?P`
K7  
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。 7,o7Cf2z

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： 6SkaH<-&K  
1. 在FRED脚本编辑界面找到参考. xF'EiX~  
2. 找到Matlab Automation Server Type Library ,/F~Y&1I  
3. 将名字改为MLAPP .j0$J\:i

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。 "$^ ~!1~

现在将脚本代码公布如下，此脚本执行如下几个步骤： m@v\(rT.  
1. 创建Matlab服务器。 ~KX/ Ai  
2. 移动探测面对于前一聚焦面的位置。 xy[3u?,&s!  
3. 在探测面追迹光线 SsDmoEeB[  
4. 在探测面计算照度 Vaw+.sG`AP  
5. 使用PutWorkspaceData发送照度数据到Matlab ,f'CD{E  
6. 使用PutFullMatrix发送标量场数据到Matlab中 @,7GaK\  
7. 用Matlab画出照度数据 L+i=VGm0  
8. 在Matlab计算照度平均值 k(G^z   
9. 返回数据到FRED中 f+)L#>Gl?
