[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。 s=n4'`y1  
f(|k0$EIu  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： %b^4XTz  
enableservice('AutomationServer', true) 6j|Ncv  
enableservice('AutomationServer') g{
]6*`/Z  
Z`tmuu  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 oPmz$]_Z

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： Km(i}:6"  
1. 在FRED脚本编辑界面找到参考. 3<^Up1CaZ  
2. 找到Matlab Automation Server Type Library > ubq{'  
3. 将名字改为MLAPP q%4X1 W

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。 4^W!,@W

现在将脚本代码公布如下，此脚本执行如下几个步骤： |E1U$,s~u  
1. 创建Matlab服务器。 xT+_JT65  
2. 移动探测面对于前一聚焦面的位置。 0&,D&y%  
3. 在探测面追迹光线 Lm4`O%  
4. 在探测面计算照度 fmuh9Z  
5. 使用PutWorkspaceData发送照度数据到Matlab unFRfec{  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ^N/d`IAjv  
7. 用Matlab画出照度数据 ,&UKsrs_  
8. 在Matlab计算照度平均值 bSsg`  
9. 返回数据到FRED中 6MVu"0#
