[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。 i!JSEQ_8  
,O^kZ}b  
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： 2JeEmG9  
enableservice('AutomationServer', true) l+`CgYo  
enableservice('AutomationServer') 8F)9.s,*  
LS#_K-  
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。 Q'ib7R;V,  
KM^}d$x}s  
在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： yd45y}uS;F  
1. 在FRED脚本编辑界面找到参考. _$HCNFdh  
2. 找到Matlab Automation Server Type Library KO}TCa  
3. 将名字改为MLAPP h4ghMBo%

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。 7-9HCP

现在将脚本代码公布如下，此脚本执行如下几个步骤： `@:k*d  
1. 创建Matlab服务器。 ms+gq
 
2. 移动探测面对于前一聚焦面的位置。 #\z"k<{*  
3. 在探测面追迹光线 {w99~?  
4. 在探测面计算照度 I;P! 
 
5. 使用PutWorkspaceData发送照度数据到Matlab =)Goip  
6. 使用PutFullMatrix发送标量场数据到Matlab中 [{ A5BE -  
7. 用Matlab画出照度数据 d+8|aS<A  
8. 在Matlab计算照度平均值 SQuW`EHBgs  
9. 返回数据到FRED中 @Hp=xC9V
