[推荐]FRED案例-FRED如何调用Matlab [复制链接]

x)jc  
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。 tmd{Gx}c  
XXw>h4hl  
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： EK.n $  
enableservice('AutomationServer', true) 5g%D0_e5  
    enableservice('AutomationServer') URbHVPCPb  
+[ng99p  
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。 "8p<NsU

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： xS4?M<|L63  
1. 在FRED脚本编辑界面找到参考. "S+AkLe(  
2. 找到Matlab Automation Server Type Library s)jNP\

    3. 将名字改为MLAPP :N!s@6

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。 #qu;{I#W3

1. 创建Matlab服务器。 L&KL]n  
2. 移动探测面对于前一聚焦面的位置。 (}5};v  
3. 在探测面追迹光线 e(?1`1  
4. 在探测面计算照度 *k,{[b  
5. 使用PutWorkspaceData发送照度数据到Matlab ~W-l|-eogz  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `z`=!1  
7. 用Matlab画出照度数据 EERCb%M8Z  
8. 在Matlab计算照度平均值 L#?mPF  
9. 返回数据到FRED中 nq,:UYNJ
