[推荐]FRED案例-FRED如何调用Matlab [复制链接]

{[Y7h}7  
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。 =h|cs{eT\2  
5/h-Hr  
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： G{>PYLxOb  
enableservice('AutomationServer', true) .sM,U  
    enableservice('AutomationServer') FeO1%#2<y  
J-uQF|   
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。 M l@F  
mEi(DW)(  
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： -{9mctt/gE  
1. 在FRED脚本编辑界面找到参考. =>evkaj  
2. 找到Matlab Automation Server Type Library RjO0*$>h  
    3. 将名字改为MLAPP ]o0]i<:  
     &nI>`Q'

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。 }' Y)"8AIA

现在将脚本代码公布如下，此脚本执行如下几个步骤： >qr/1mW  
1. 创建Matlab服务器。 w{k^O7

2. 移动探测面对于前一聚焦面的位置。 y06**f)  
3. 在探测面追迹光线 qz3 Z'  
4. 在探测面计算照度 TecMQ0 KD  
5. 使用PutWorkspaceData发送照度数据到Matlab $ xHtI]T  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *x]*%  
7. 用Matlab画出照度数据 GbZ~eI`,2  
8. 在Matlab计算照度平均值 /je $+  
9. 返回数据到FRED中 JR15y3F
