[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。 |f+|OZY  
b,U"N-6  
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： YI!ecx%/4  
enableservice('AutomationServer', true) }nNZp  
enableservice('AutomationServer') RL0,QC)e#@  
_(=[d  
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。 eZ+pZq  
2t'^  
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： s"5f5Cn/Wh  
1. 在FRED脚本编辑界面找到参考. 1I< <`7'  
2. 找到Matlab Automation Server Type Library g_8Bhe"ik  
3. 将名字改为MLAPP NUH;\*]8s

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。 lt 74`9,f

现在将脚本代码公布如下，此脚本执行如下几个步骤： p^1s9CM%  
1. 创建Matlab服务器。 )Zx;Z[  
2. 移动探测面对于前一聚焦面的位置。 6^ UQ{P1;  
3. 在探测面追迹光线 owYf1=G  
4. 在探测面计算照度 et[n;nl>V  
5. 使用PutWorkspaceData发送照度数据到Matlab -olD!zKS  
6. 使用PutFullMatrix发送标量场数据到Matlab中 m,UMb#7Y  
7. 用Matlab画出照度数据 &~`Ay4hq  
8. 在Matlab计算照度平均值 *N5cC#5`=  
9. 返回数据到FRED中 $kPC"!X\
