[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。 n9wj[t1/  
5Bzuj`  
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： U8U/?zW/&  
enableservice('AutomationServer', true) $o
{F  
enableservice('AutomationServer') VQ
/ <09e  
WJBW:2=;  
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

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： ~rQ4n9G  
1. 在FRED脚本编辑界面找到参考. i:AjWC@]  
2. 找到Matlab Automation Server Type Library nqUH6(  
3. 将名字改为MLAPP 'aLPTVM^  
e=YO.HT  
a [0N,t  
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@Kl

现在将脚本代码公布如下，此脚本执行如下几个步骤： VuP#b'g=|]  
1. 创建Matlab服务器。 3T Yo  
2. 移动探测面对于前一聚焦面的位置。 =kyJaT^5[  
3. 在探测面追迹光线 LS*{]@8q  
4. 在探测面计算照度 $#g#[/  
5. 使用PutWorkspaceData发送照度数据到Matlab zlC^  
6. 使用PutFullMatrix发送标量场数据到Matlab中 iW1$!l>v  
7. 用Matlab画出照度数据 Z^jGT+

8. 在Matlab计算照度平均值 hXj* {vT  
9. 返回数据到FRED中 '|h./.K
