[推荐]FRED案例-FRED如何调用Matlab [复制链接]

ckP&N:tC  
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。 |^Try2@  
t?28s/?  
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： ~zRUJ2hD!  
enableservice('AutomationServer', true) T#J]%IDd  
    enableservice('AutomationServer') INW8Q`[F  
)<DL'  
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。 tNbCO+rZ

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： &AGV0{NMh]  
1. 在FRED脚本编辑界面找到参考. RK/SeS  
2. 找到Matlab Automation Server Type Library : i3-7k  
    3. 将名字改为MLAPP zi2hi9A  
     "Fc
A:7+

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。 S#!PDg

现在将脚本代码公布如下，此脚本执行如下几个步骤： U;OJ.a9  
1. 创建Matlab服务器。 QtkyKR  
2. 移动探测面对于前一聚焦面的位置。 iK(n'X5i  
3. 在探测面追迹光线 yXc/Nl%  
4. 在探测面计算照度 ],>Z'W  
5. 使用PutWorkspaceData发送照度数据到Matlab eXnMS!g%Z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @luv
;X^%  
7. 用Matlab画出照度数据 p8[Z/]p  
8. 在Matlab计算照度平均值 jFw?Ky2  
9. 返回数据到FRED中 0u QqPF t
