[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。 xd<68%Cn  
} _z~:{Y  
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： 6}$cDk`dz  
enableservice('AutomationServer', true) 9qA_5x%"%u  
enableservice('AutomationServer') V-3]h ba,  
dX=^>9hN/  
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。 W+X zU"l

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： add-]

1. 在FRED脚本编辑界面找到参考. 0 CS_-  
2. 找到Matlab Automation Server Type Library =@>&kU%$&  
3. 将名字改为MLAPP i1C'

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。 ZlzFmNe60

现在将脚本代码公布如下，此脚本执行如下几个步骤： (x@"Dp=MZW  
1. 创建Matlab服务器。 Zj;!7ZuT1  
2. 移动探测面对于前一聚焦面的位置。 y6oDbwke  
3. 在探测面追迹光线 XEI]T~  
4. 在探测面计算照度 {ex]_V>  
5. 使用PutWorkspaceData发送照度数据到Matlab nDvWOt  
6. 使用PutFullMatrix发送标量场数据到Matlab中 T5h[{J^  
7. 用Matlab画出照度数据 b+>godTi_  
8. 在Matlab计算照度平均值 K0]Wb=v  
9. 返回数据到FRED中 BJ5#!I%h
