[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。 W{RZ@3ZY  
"_^vQ1M]Z  
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：
LUs)"ZAi|  
enableservice('AutomationServer', true) |`|#-xu  
enableservice('AutomationServer') .
}9Lj  
%g_)_ ~  
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。 `.z"Q%uz

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： aP$it6Z  
1. 在FRED脚本编辑界面找到参考. ty8>(N(~  
2. 找到Matlab Automation Server Type Library &t~NR$@  
3. 将名字改为MLAPP vX@TZet0

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。 l|81_BC"

现在将脚本代码公布如下，此脚本执行如下几个步骤： hpc&s  
1. 创建Matlab服务器。 $l $p|  
2. 移动探测面对于前一聚焦面的位置。 tzShds  
3. 在探测面追迹光线 ;kI)j ?  
4. 在探测面计算照度 b/{$#[oP`  
5. 使用PutWorkspaceData发送照度数据到Matlab x2,;ar\D  
6. 使用PutFullMatrix发送标量场数据到Matlab中 J!Q #x
s  
7. 用Matlab画出照度数据 0u;a*#V@  
8. 在Matlab计算照度平均值 #iKPp0`K*  
9. 返回数据到FRED中 })+iAxR
