[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。 `fY~Lv{4d_  
e@NS=U` <  
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： R l^ENrv!]  
enableservice('AutomationServer', true) o*'J8El\y^  
enableservice('AutomationServer') @m1vB!  
m~(]\  
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。 &N[~+"

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： "_}Hzpy5k  
1. 在FRED脚本编辑界面找到参考. V78QV3  
2. 找到Matlab Automation Server Type Library ]wER&/v"  
3. 将名字改为MLAPP Do=*bZ;A

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。 #gUM%$

1. 创建Matlab服务器。 ) e;)9~  
2. 移动探测面对于前一聚焦面的位置。 6^if%62l&  
3. 在探测面追迹光线 ,l.O @  
4. 在探测面计算照度 UF|v=|*{#  
5. 使用PutWorkspaceData发送照度数据到Matlab eH(

6. 使用PutFullMatrix发送标量场数据到Matlab中 iVFHr<zk  
7. 用Matlab画出照度数据 O5{ >k  
8. 在Matlab计算照度平均值 b U-C

9. 返回数据到FRED中 zX{
