[技术]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。 +>44'M^Z|(  
X<#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： BqCBH!^x  
enableservice('AutomationServer', true) &]16Hb~  
enableservice('AutomationServer') %
RdCSQ9~  
~ 9^
1m  
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。 j'X]bd'  
.Rd@,3  
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： B9>3xxp(by  
1. 在FRED脚本编辑界面找到参考. =HQH;c"  
2. 找到Matlab Automation Server Type Library >|XQfavE  
3. 将名字改为MLAPP ]Tx8ImD#)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。 7'J}|m{7

现在将脚本代码公布如下，此脚本执行如下几个步骤： UyEyk$6SU  
1. 创建Matlab服务器。 n;xtUw6\  
2. 移动探测面对于前一聚焦面的位置。 Uj(,

3. 在探测面追迹光线 }f;Zx)!  
4. 在探测面计算照度 iNT

5. 使用PutWorkspaceData发送照度数据到Matlab r*p<7  
6. 使用PutFullMatrix发送标量场数据到Matlab中 zX{
[Z  
7. 用Matlab画出照度数据 .B6$U>>NS^  
8. 在Matlab计算照度平均值 g(;t,Vy,I  
9. 返回数据到FRED中 )DI/y1
