[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。 cNl NJ  
>r\q6f#J4  
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： =n<Lbl(7  
enableservice('AutomationServer', true) c:I %j
m  
enableservice('AutomationServer') Q].p/-[(  
 <BiSx  
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。 \k 6'[ln

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： 363KU@`  
1. 在FRED脚本编辑界面找到参考. _J"fgxW  
2. 找到Matlab Automation Server Type Library eXQLE]L]  
3. 将名字改为MLAPP rU9z? (  
y|/[;  
`Kbf]"4q  
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。 dym K@

现在将脚本代码公布如下，此脚本执行如下几个步骤： U'aJCM  
1. 创建Matlab服务器。 +L|x^B3  
2. 移动探测面对于前一聚焦面的位置。 !nU
|3S[b  
3. 在探测面追迹光线 PW_"JZ  
4. 在探测面计算照度 c!ieN9^+  
5. 使用PutWorkspaceData发送照度数据到Matlab fSVb.MZa7  
6. 使用PutFullMatrix发送标量场数据到Matlab中 H/U.Bg 4  
7. 用Matlab画出照度数据 bae;2| w  
8. 在Matlab计算照度平均值 6Ts[NXa  
9. 返回数据到FRED中 />n!2'!
