[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。 A{\7HV5  
}qT @.  
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： ui`xgR\6Rh  
enableservice('AutomationServer', true) 
5.F.mUO  
enableservice('AutomationServer') Qbfm*JP~  
au}rS0)+  
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。 Y}'C'PR

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：
\bqNjlu  
1. 在FRED脚本编辑界面找到参考. |M`B  
2. 找到Matlab Automation Server Type Library Yi&;4vC  
3. 将名字改为MLAPP TbU\qcm]]

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。 lZV]Z3=p'0

现在将脚本代码公布如下，此脚本执行如下几个步骤： rw8O<No4.o  
1. 创建Matlab服务器。 t*zve,?}  
2. 移动探测面对于前一聚焦面的位置。 gWqmK/.U.0  
3. 在探测面追迹光线 jpZX5_o  
4. 在探测面计算照度 aoz+g,1 //  
5. 使用PutWorkspaceData发送照度数据到Matlab HnUM:-6  
6. 使用PutFullMatrix发送标量场数据到Matlab中 kf_s.Dedw  
7. 用Matlab画出照度数据 \% !]qv  
8. 在Matlab计算照度平均值 f'TjR#w  
9. 返回数据到FRED中 03J,NXs
