[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。 ynOc~TN  
vl#V-UW$4P  
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： bOnukbJ  
enableservice('AutomationServer', true) Yc|-sEK/  
enableservice('AutomationServer') Yp?a=R  
h:US]ZC^Z  
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。 <9MQ

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： $yR{ZFo  
1. 在FRED脚本编辑界面找到参考. s525`Q;  
2. 找到Matlab Automation Server Type Library 6i?kkULBS  
3. 将名字改为MLAPP 0X}w[^f  
l")o!N?  
Bt`r6v;\  
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。 `qYc#_ELv

现在将脚本代码公布如下，此脚本执行如下几个步骤： plz=G}Y  
1. 创建Matlab服务器。 [3bwbfHhi  
2. 移动探测面对于前一聚焦面的位置。 *SAcH_I2$>  
3. 在探测面追迹光线 m-pIFL<^N  
4. 在探测面计算照度 +$pO  
5. 使用PutWorkspaceData发送照度数据到Matlab E!(`275s  
6. 使用PutFullMatrix发送标量场数据到Matlab中 JqH.QnKcv  
7. 用Matlab画出照度数据 )Sh;UW  
8. 在Matlab计算照度平均值 @?($j)9}  
9. 返回数据到FRED中 `(w kqa
