[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。 +7<>x-+

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： (E}cA&{  
enableservice('AutomationServer', true) >DUE8hp;<  
enableservice('AutomationServer') &9_\E{o%]  
Gi2ad+QH-  
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。 ([CnYv

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： *tM7>  
1. 在FRED脚本编辑界面找到参考. E:4P1,%01+  
2. 找到Matlab Automation Server Type Library 0 ;_wAk  
3. 将名字改为MLAPP L sDzV)

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。 sMS9!{A

1. 创建Matlab服务器。

2. 移动探测面对于前一聚焦面的位置。 a5}44/%  
3. 在探测面追迹光线 '<&EPUO  
4. 在探测面计算照度 7vpN6YP  
5. 使用PutWorkspaceData发送照度数据到Matlab u:u

6. 使用PutFullMatrix发送标量场数据到Matlab中 *Qg5Z   
7. 用Matlab画出照度数据 f;Bfh3  
8. 在Matlab计算照度平均值 !jnqA Z  
9. 返回数据到FRED中 .5!sOOs$P
