[技术]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。 inBBU[Sl  
$RfM}!7?  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： *am.NH\  
enableservice('AutomationServer', true) ]2+7?QL,  
enableservice('AutomationServer') c
F7I  
]4
ya$%A  
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。 j ~:Dr  
CD;C
z*c  
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： i"p)%q~ z  
1. 在FRED脚本编辑界面找到参考. qe8dpI;  
2. 找到Matlab Automation Server Type Library !U/iY%NE  
3. 将名字改为MLAPP 6Xu8~%i

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。 h/j+b.|

现在将脚本代码公布如下，此脚本执行如下几个步骤： Z_.Eale^  
1. 创建Matlab服务器。 s_}T-%\  
2. 移动探测面对于前一聚焦面的位置。 KWq7M8mq  
3. 在探测面追迹光线 `L/kwVl  
4. 在探测面计算照度
yCy4t6`e  
5. 使用PutWorkspaceData发送照度数据到Matlab Mhc!v, D$  
6. 使用PutFullMatrix发送标量场数据到Matlab中 gNY}`'~hr  
7. 用Matlab画出照度数据 wws)**]J8  
8. 在Matlab计算照度平均值 M.iR5Uh  
9. 返回数据到FRED中 RcIGIt
