[推荐]FRED案例-FRED如何调用Matlab [复制链接]

<f7?PAd  
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。 it(LphB8  
JoZqLy!@
 
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： 2z'+1+B'  
enableservice('AutomationServer', true) aQ.Iq  
    enableservice('AutomationServer') LEYWH%y  
`'z(--J}`  
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。 *ah>-}-  
( rA\_FOJ  
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： 2#>$%[  
1. 在FRED脚本编辑界面找到参考. *ge].E  
2. 找到Matlab Automation Server Type Library UN cYu9[  
    3. 将名字改为MLAPP \[Sm2/9v  
     FQ;4'B^k]

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。 1x~%Ydy

现在将脚本代码公布如下，此脚本执行如下几个步骤： .`oJcJ  
1. 创建Matlab服务器。 *(?U  
2. 移动探测面对于前一聚焦面的位置。 nz,Mqol  
3. 在探测面追迹光线 ig2{lEkF  
4. 在探测面计算照度 .V5q$5j  
5. 使用PutWorkspaceData发送照度数据到Matlab $nUd\B$.=  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8m#}S\m  
7. 用Matlab画出照度数据 ,pQ'w7  
8. 在Matlab计算照度平均值 ?noETHz)  
9. 返回数据到FRED中 \iFMU#
