[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。 <B=!ZC=n

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： `Ef&h V  
enableservice('AutomationServer', true) Gj(UA1~1  
enableservice('AutomationServer') D[iIj_CKQ  
hR3Pa'/i  
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。 ;3k6_ub

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： DU: sQS4  
1. 在FRED脚本编辑界面找到参考. Zjh9jvsW  
2. 找到Matlab Automation Server Type Library DozC>  
3. 将名字改为MLAPP !B\[Q$

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。 >5!/&D.q

1. 创建Matlab服务器。 r

2. 移动探测面对于前一聚焦面的位置。 Fttny]  
3. 在探测面追迹光线 MB,P#7|  
4. 在探测面计算照度 hrr;=q$  
5. 使用PutWorkspaceData发送照度数据到Matlab ,w/f:-y  
6. 使用PutFullMatrix发送标量场数据到Matlab中 6uH1dsD  
7. 用Matlab画出照度数据 4$+9k;m'  
8. 在Matlab计算照度平均值 @tLoU%  
9. 返回数据到FRED中 8Bnw//_pT
