[推荐]FRED案例-FRED如何调用Matlab [复制链接]

s)~Q@ze2  
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。 n+Fl|4  
3o"~_l$z  
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： 5x=tOR/h  
enableservice('AutomationServer', true) ZiVTc/b  
    enableservice('AutomationServer') {^MR^4&}(  
pZjyzH{~  
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#F;eK2pf

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. B0Xn9Tvk  
2. 找到Matlab Automation Server Type Library r

    3. 将名字改为MLAPP 5-=mtvA:

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。

现在将脚本代码公布如下，此脚本执行如下几个步骤： TyGXDU  
1. 创建Matlab服务器。 7CrWsQl u  
2. 移动探测面对于前一聚焦面的位置。 Q8z>0ci3o  
3. 在探测面追迹光线 i&"I/!3Q@  
4. 在探测面计算照度 /PHktSG  
5. 使用PutWorkspaceData发送照度数据到Matlab (Ozb+W?  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 |W\CV0L2  
7. 用Matlab画出照度数据 s{$c8  
8. 在Matlab计算照度平均值 4i/TEHQ  
9. 返回数据到FRED中 8h;1(S)*Z
