[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。 ~7anj.  
z]7/Gc,j  
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： Dxy^r*B  
enableservice('AutomationServer', true) J$5Vjh'aM
 
enableservice('AutomationServer') |az2vD6P  
v7n@CWnN  
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。 ,l Y4WO

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： .5uqc.i"f  
1. 在FRED脚本编辑界面找到参考. F$bV}>-1k  
2. 找到Matlab Automation Server Type Library h+ud[atk.  
3. 将名字改为MLAPP /3&MUB*z&y

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。 P?S]Q19Q4

3. 在探测面追迹光线 T7%!JBg

4. 在探测面计算照度 LT"H-fTgs  
5. 使用PutWorkspaceData发送照度数据到Matlab ^GyZycch  
6. 使用PutFullMatrix发送标量场数据到Matlab中 $xWUzg1<U  
7. 用Matlab画出照度数据 vd)zvI  
8. 在Matlab计算照度平均值 \5 rJ  
9. 返回数据到FRED中 k/D{&(F ~
