[推荐]FRED案例-FRED如何调用Matlab [复制链接]

q:iu hI$~G  
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。 >ffC?5+

})zRL0!'  
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： v(Sh+p  
enableservice('AutomationServer', true) .b^!f<j  
    enableservice('AutomationServer') joZd  
6o5,d]  
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。 2iOYC0`!

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： uY/CiTWr  
1. 在FRED脚本编辑界面找到参考. XD_!5+\H1  
2. 找到Matlab Automation Server Type Library |`{$Ego:  
    3. 将名字改为MLAPP 6:`[Fi  
     J+N -+,,  
     IY mkZ?cW  
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。 qElPYN*wF

现在将脚本代码公布如下，此脚本执行如下几个步骤： G|"m-.9F  
1. 创建Matlab服务器。 82?LZ?!PD  
2. 移动探测面对于前一聚焦面的位置。 UdA,.C0  
3. 在探测面追迹光线 |L:X$oM  
4. 在探测面计算照度 p<wC{D  
5. 使用PutWorkspaceData发送照度数据到Matlab !C^>

    6. 使用PutFullMatrix发送标量场数据到Matlab中 )e6sg]#  
7. 用Matlab画出照度数据 }m7$,'C%P  
8. 在Matlab计算照度平均值 v$5D&Tv  
9. 返回数据到FRED中 jc#gn&4C
