[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。 CC#;c1t  
bFe+m1Q_  
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： ,lZB96r0  
enableservice('AutomationServer', true) j@YU|-\qh  
enableservice('AutomationServer') yE}}c{hSn  
 GB$;n?  
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。 uV!^,,~

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： C:PMewn  
1. 在FRED脚本编辑界面找到参考. ]IoUwgpI)  
2. 找到Matlab Automation Server Type Library q Y

3. 将名字改为MLAPP ?b(=1S\E'^

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。 xuqv6b.

现在将脚本代码公布如下，此脚本执行如下几个步骤： D#3\y*-y?  
1. 创建Matlab服务器。 qWQ/'M  
2. 移动探测面对于前一聚焦面的位置。 Q_[ 3`jl  
3. 在探测面追迹光线 3AU;>D^5  
4. 在探测面计算照度 7

5. 使用PutWorkspaceData发送照度数据到Matlab V5UF3'3;}  
6. 使用PutFullMatrix发送标量场数据到Matlab中 _f$^%?^  
7. 用Matlab画出照度数据 <StN%2WQ1  
8. 在Matlab计算照度平均值 <1uZa  
9. 返回数据到FRED中 r"P|dlV-
