[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。 V)?g4M3}  
Q ?<9  
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： FO3*[O   
enableservice('AutomationServer', true) mqxy(zS]  
enableservice('AutomationServer') |xC TX  
\r&@3a.>  
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。 !!pi\J?sk

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： d|HM
 
1. 在FRED脚本编辑界面找到参考. 0X6o  
2. 找到Matlab Automation Server Type Library YR`rg;n#  
3. 将名字改为MLAPP M?CMN.Dw

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。 QAw,XZ.K^

现在将脚本代码公布如下，此脚本执行如下几个步骤： j ZafwBi  
1. 创建Matlab服务器。 (NlEb'~+  
2. 移动探测面对于前一聚焦面的位置。 $S("-3  
3. 在探测面追迹光线 n#,l&Bx  
4. 在探测面计算照度 kV<)>Gs  
5. 使用PutWorkspaceData发送照度数据到Matlab X Y?@

6. 使用PutFullMatrix发送标量场数据到Matlab中 N*-Z Jv  
7. 用Matlab画出照度数据 D'+8]B  
8. 在Matlab计算照度平均值 B)NB6dCp  
9. 返回数据到FRED中 jg/<"/E
