[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。

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： 16Jq*hKU  
enableservice('AutomationServer', true) jx}'M$TA  
enableservice('AutomationServer') &Cv  
83SK<V6  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 9Dgs A`{$

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： e\cyiW0  
1. 在FRED脚本编辑界面找到参考. oKCy,Ot<  
2. 找到Matlab Automation Server Type Library ;nP(S`'  
3. 将名字改为MLAPP lTP#6zqfv

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。 )\EIXTZY=

现在将脚本代码公布如下，此脚本执行如下几个步骤： VOM@x%6#c  
1. 创建Matlab服务器。 ?z#*eoPr  
2. 移动探测面对于前一聚焦面的位置。 "q+Z*  
3. 在探测面追迹光线 V%PQlc.X  
4. 在探测面计算照度
aG^E^^Y  
5. 使用PutWorkspaceData发送照度数据到Matlab BK+P  
6. 使用PutFullMatrix发送标量场数据到Matlab中 cI@qt>&  
7. 用Matlab画出照度数据 T+&fUhSy  
8. 在Matlab计算照度平均值 1xd6p  
9. 返回数据到FRED中 a-Y6ghs
