[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。 DYy@t^sC  
0C4*F  
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： K-g=td/@  
enableservice('AutomationServer', true) MSxU>FX0  
enableservice('AutomationServer') q\{;_?a  
g/n"N>L  
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。 @E&X&F%  
(_s!,QUe  
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： jS5t?0  
1. 在FRED脚本编辑界面找到参考. AOvH&9**  
2. 找到Matlab Automation Server Type Library +E""8kW- Z  
3. 将名字改为MLAPP 9fr&Yb=_o@

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。 S%a}ip&

现在将脚本代码公布如下，此脚本执行如下几个步骤： p!rGPyGC  
1. 创建Matlab服务器。 ^YB\\a9  
2. 移动探测面对于前一聚焦面的位置。 Vt$ $ceu  
3. 在探测面追迹光线 q(${jz4w  
4. 在探测面计算照度 [8om9 Z3  
5. 使用PutWorkspaceData发送照度数据到Matlab Q>+_W2~]  
6. 使用PutFullMatrix发送标量场数据到Matlab中 7\Yq]:;O  
7. 用Matlab画出照度数据 0lJBtk9wn  
8. 在Matlab计算照度平均值 <)0LwkFtB  
9. 返回数据到FRED中 <iY 9cV|}3
