[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。 `uC^"R(m  
$i1:--~2\  
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： ~i!I6d~  
enableservice('AutomationServer', true) .yD5>iBh  
enableservice('AutomationServer') 4'Ya-xx  
<k{_YRB  
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。 g!OcWy)7

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： ppGWh  
1. 在FRED脚本编辑界面找到参考. [I/ZzDMX
 
2. 找到Matlab Automation Server Type Library gw^W6v  
3. 将名字改为MLAPP .9?GKD  
1L?d/j  
&MPlSIg  
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。 (-`PO]e48

现在将脚本代码公布如下，此脚本执行如下几个步骤： 6OqF-nso[E  
1. 创建Matlab服务器。 3*\hGt,ZP  
2. 移动探测面对于前一聚焦面的位置。 &h_Y?5kK  
3. 在探测面追迹光线

4. 在探测面计算照度 G

5. 使用PutWorkspaceData发送照度数据到Matlab c'mg=jH  
6. 使用PutFullMatrix发送标量场数据到Matlab中 9$D}j"  
7. 用Matlab画出照度数据 g:@4/+TSt  
8. 在Matlab计算照度平均值 bh#6yvpMR  
9. 返回数据到FRED中 *Uy;P>8
