[推荐]FRED案例-FRED如何调用Matlab [复制链接]

KM jnY2  
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。 y_A?}'X  
-|x YT+?%  
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： F\(7B#  
enableservice('AutomationServer', true) KuohUH+  
    enableservice('AutomationServer') **L3T3$)  
8w]>SEGFs  
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。 JHIXTy__

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： /aHx'TG  
1. 在FRED脚本编辑界面找到参考. hDc)\vzr  
2. 找到Matlab Automation Server Type Library jFThW N  
    3. 将名字改为MLAPP ^tY$pPA

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。 \QKr2|

现在将脚本代码公布如下，此脚本执行如下几个步骤： Vuu_Sd  
1. 创建Matlab服务器。 :U$U:e  
2. 移动探测面对于前一聚焦面的位置。 cgvD>V

3. 在探测面追迹光线 2lm{:tS  
4. 在探测面计算照度 #ZS8}X*S  
5. 使用PutWorkspaceData发送照度数据到Matlab I}{Xv#@o  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !ii'hwFm$  
7. 用Matlab画出照度数据 Up|>)WFw"  
8. 在Matlab计算照度平均值 q\gvX 76a  
9. 返回数据到FRED中 Z/>0P*
