[推荐]FRED案例-FRED如何调用Matlab [复制链接]

^)&Ly_xrU  
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。 bTZ>@~$
 
C=fsJ=a5;  
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： $/u1chf  
enableservice('AutomationServer', true) 5Z/yhF.{  
    enableservice('AutomationServer') Dt.0YKF  
8YNu<   
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。 =%!e(N'p  
MaZM%W8Z  
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： A0G)imsW:_  
1. 在FRED脚本编辑界面找到参考. YiD-F7hf.*  
2. 找到Matlab Automation Server Type Library kmryu
=  
    3. 将名字改为MLAPP "r u]?{v  
     ]b3/Es+  
     >A-<ZS*N  
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。 M70c{s`w5

现在将脚本代码公布如下，此脚本执行如下几个步骤： h@=7R  
1. 创建Matlab服务器。 ]1m"V;vZ  
2. 移动探测面对于前一聚焦面的位置。 J , V  
3. 在探测面追迹光线 MR`:5e  
4. 在探测面计算照度 wMGk!N  
5. 使用PutWorkspaceData发送照度数据到Matlab OFA{ KZga  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 VZ$=6CavH  
7. 用Matlab画出照度数据 7W"/N#G  
8. 在Matlab计算照度平均值 [r(Qs|  
9. 返回数据到FRED中 #O"
