[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。 `H! (hMMV  
.)tv'V/  
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： x$d[Ovw-  
enableservice('AutomationServer', true) v
Fk@  
enableservice('AutomationServer') . Vb|le(7  
}k }=e  
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。 3'uXU<W!

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： GJ%^hr`P  
1. 在FRED脚本编辑界面找到参考. }h^ fX  
2. 找到Matlab Automation Server Type Library A]bQUWt2  
3. 将名字改为MLAPP bYP8

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。 p:xyy*I

现在将脚本代码公布如下，此脚本执行如下几个步骤： E>_Rsw *  
1. 创建Matlab服务器。 b\"F6TF:  
2. 移动探测面对于前一聚焦面的位置。 (u 7Lh>6%  
3. 在探测面追迹光线 O!"K'Bm  
4. 在探测面计算照度 Y~}MfRE3z  
5. 使用PutWorkspaceData发送照度数据到Matlab Ir JSU_  
6. 使用PutFullMatrix发送标量场数据到Matlab中 $+WXM$N  
7. 用Matlab画出照度数据 @}q, ';H7  
8. 在Matlab计算照度平均值 PlB3"{}0Q  
9. 返回数据到FRED中 ZjxF@`H
