[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。 j{0_K+B  
C5\bnk{  
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： wH
3FCfvm  
enableservice('AutomationServer', true) BPIp3i  
enableservice('AutomationServer') Ma:xxsH.  
0:@:cz=#*  
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。 P'KaWu9z

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： lnEc5J@c>i  
1. 在FRED脚本编辑界面找到参考. 8h78Zb&[  
2. 找到Matlab Automation Server Type Library W0K&mBu  
3. 将名字改为MLAPP "/[-U;ck

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。 PBTGN;y

现在将脚本代码公布如下，此脚本执行如下几个步骤： 7,d^?.~S  
1. 创建Matlab服务器。 KCGs*kp>  
2. 移动探测面对于前一聚焦面的位置。 <bDjAVq  
3. 在探测面追迹光线 TSt-#c4B  
4. 在探测面计算照度 #U{^L{1Gx  
5. 使用PutWorkspaceData发送照度数据到Matlab -ytSS:|%\  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ! %S9H2Lv  
7. 用Matlab画出照度数据 @f{yx\u/  
8. 在Matlab计算照度平均值 P>z k  
9. 返回数据到FRED中 ,]w-!I
