[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。 s<Fl p  
4fzZ;2sl}  
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： >3_Gw4S*H  
enableservice('AutomationServer', true) :L;a:xSpn=  
enableservice('AutomationServer') L-\GHu~)  
TPY}C  
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。 0;ji65

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： 'QIqBU'~  
1. 在FRED脚本编辑界面找到参考. $g7<Y*t[  
2. 找到Matlab Automation Server Type Library ]~nKK@Rw  
3. 将名字改为MLAPP Lp7SLkwh3M

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。 Y<rU#Z#T

现在将脚本代码公布如下，此脚本执行如下几个步骤： _?OG1t!  
1. 创建Matlab服务器。 9S-9.mvop  
2. 移动探测面对于前一聚焦面的位置。 PuO&wI]:  
3. 在探测面追迹光线 j)GtEP<n#  
4. 在探测面计算照度 HdG2X  
5. 使用PutWorkspaceData发送照度数据到Matlab @vB!u[{  
6. 使用PutFullMatrix发送标量场数据到Matlab中 )0R'(#  
7. 用Matlab画出照度数据 eIo7F m  
8. 在Matlab计算照度平均值 ^KELKv,_  
9. 返回数据到FRED中 Ow077v?
