[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。 Xv!Gg6v6  
`W)?d I?#M  
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： LhAW|];  
enableservice('AutomationServer', true) y]@JkF(  
enableservice('AutomationServer') *Xk5H,:  

}gXhN"  
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。 sHBTB6)lx

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：

1. 在FRED脚本编辑界面找到参考. V^Z5i]zT  
2. 找到Matlab Automation Server Type Library !~?/D  
3. 将名字改为MLAPP C=&n1/

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。 Ip7#${f5M

现在将脚本代码公布如下，此脚本执行如下几个步骤： /Lr`Aka5  
1. 创建Matlab服务器。 <v -YMk@  
2. 移动探测面对于前一聚焦面的位置。 ZlC+DXg#S  
3. 在探测面追迹光线 8f~x\.  
4. 在探测面计算照度 L%$-?O|  
5. 使用PutWorkspaceData发送照度数据到Matlab B`R@%US  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ]3,9."^  
7. 用Matlab画出照度数据 @R`6jS_gK  
8. 在Matlab计算照度平均值 Ua|iAD1  
9. 返回数据到FRED中 .+XK>jl+
