[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。 L&=r-\.ev

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： 7+KI9u}-  
enableservice('AutomationServer', true) 7hLh}  
enableservice('AutomationServer') >Y\?v-^~;  
,h/l-#KS  
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。 e7-IqQA{3C

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： #Jp|Cb<qx  
1. 在FRED脚本编辑界面找到参考. eR`Q7]j] -  
2. 找到Matlab Automation Server Type Library ^qVBgBPb  
3. 将名字改为MLAPP A@:U|)+4

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。 3xdJ<Lrq

现在将脚本代码公布如下，此脚本执行如下几个步骤： ([^f1;ncm  
1. 创建Matlab服务器。 @CxgoX^  
2. 移动探测面对于前一聚焦面的位置。 QctzIC#;k  
3. 在探测面追迹光线 #W.vX=/*  
4. 在探测面计算照度 yc`3)  
5. 使用PutWorkspaceData发送照度数据到Matlab @,2,(=l*C  
6. 使用PutFullMatrix发送标量场数据到Matlab中 <5#2^

7. 用Matlab画出照度数据 \L}7.fkb8  
8. 在Matlab计算照度平均值 f+1'Ah0'

9. 返回数据到FRED中 5:5d=7WX
