[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。 y2:Bv2}  
YE[{Y(5;q  
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： .Dt.7G  
enableservice('AutomationServer', true) (Z#j^}G_
l  
enableservice('AutomationServer') CQI\/oaO  
jFGY`9Zw0  
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。 0khAi|PY

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： 8 _|"+Ze  
1. 在FRED脚本编辑界面找到参考. )(W%Hmi  
2. 找到Matlab Automation Server Type Library 'tMS5d)4:  
3. 将名字改为MLAPP 2,e>gP\]

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。 yPT\9"/

1. 创建Matlab服务器。 4

2. 移动探测面对于前一聚焦面的位置。 &D#B"XI  
3. 在探测面追迹光线 g7

4. 在探测面计算照度 $##

5. 使用PutWorkspaceData发送照度数据到Matlab "J*LR  
6. 使用PutFullMatrix发送标量场数据到Matlab中 2/RW(U  
7. 用Matlab画出照度数据 *FC26_pH  
8. 在Matlab计算照度平均值 b*dEX%H8sf  
9. 返回数据到FRED中 3TF'[(K=
