[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。 ?#xl3Z ;I  
e+ xQ\LH  
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： +#O+%!  
enableservice('AutomationServer', true) ><V*`{bD9)  
enableservice('AutomationServer') v+c>iI  
@/2Kfr  
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。 9T,/R1N8  
Dg&84,bv^  
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： -yqsJGY
 
1. 在FRED脚本编辑界面找到参考. 7T~M`$h  
2. 找到Matlab Automation Server Type Library f:c'j`  
3. 将名字改为MLAPP F:{*4b  
k+<945kC  
Hbm 4oYN  
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。 %fS9F^AK

现在将脚本代码公布如下，此脚本执行如下几个步骤： %@$UIO,(  
1. 创建Matlab服务器。 S-Uod y  
2. 移动探测面对于前一聚焦面的位置。 sZ;|NAx)  
3. 在探测面追迹光线 X>q`F;W  
4. 在探测面计算照度 ]WT@&F  
5. 使用PutWorkspaceData发送照度数据到Matlab Q7%4`_$!  
6. 使用PutFullMatrix发送标量场数据到Matlab中 7[m?\/K~  
7. 用Matlab画出照度数据 SZykG
[  
8. 在Matlab计算照度平均值 H4/wO  
9. 返回数据到FRED中 c9(3z0!F?
