[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。 k-\RdX)E  
2M+'9+k~  
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： [O(8
izv  
enableservice('AutomationServer', true) DU-&bm  
enableservice('AutomationServer') ]Syr{|  
2:l8RH!Y  
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。 xA2"i2k9  
>~k"C,6
 
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： QWV12t$v  
1. 在FRED脚本编辑界面找到参考. m339Y2%=  
2. 找到Matlab Automation Server Type Library @s;qmBX4  
3. 将名字改为MLAPP IXef}%1N?

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。 V}kQXz"9

现在将脚本代码公布如下，此脚本执行如下几个步骤： m|w-}s,  
1. 创建Matlab服务器。 S( r Fa  
2. 移动探测面对于前一聚焦面的位置。 B#K{Y$!v  
3. 在探测面追迹光线 na1*^S`[  
4. 在探测面计算照度 G>);8T%l  
5. 使用PutWorkspaceData发送照度数据到Matlab K`?",G?_  
6. 使用PutFullMatrix发送标量场数据到Matlab中 &%Lps_+fJ  
7. 用Matlab画出照度数据 '{?7\+o.x  
8. 在Matlab计算照度平均值 3B5GsI  
9. 返回数据到FRED中 /!mF,oR!
