[技术]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。 ,'KS:`m!  
"Q>gQKgL  
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： Uzx,aYo X  
enableservice('AutomationServer', true) m4=[e!  
enableservice('AutomationServer') Tf|?j=f  
N3Yf3rK  
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。 g$(<wWsU

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： 42Qfv%*c  
1. 在FRED脚本编辑界面找到参考. Pa8E.<>  
2. 找到Matlab Automation Server Type Library YEg(QOn3Q  
3. 将名字改为MLAPP A$H;2T5N

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。 z;#DX15Rj

现在将脚本代码公布如下，此脚本执行如下几个步骤： wOlnDQs  
1. 创建Matlab服务器。 323zR*\m  
2. 移动探测面对于前一聚焦面的位置。 .:`+4n  
3. 在探测面追迹光线 "IjCuR;#  
4. 在探测面计算照度 ;aY.CgX  
5. 使用PutWorkspaceData发送照度数据到Matlab )37.H^7  
6. 使用PutFullMatrix发送标量场数据到Matlab中 pKnM=N1f  
7. 用Matlab画出照度数据 G[pDKELL  
8. 在Matlab计算照度平均值 r&MHww1i  
9. 返回数据到FRED中 ?3#W7sF
