[推荐]FRED案例-FRED如何调用Matlab [复制链接]

q^T&A[hMPx  
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。 pE YrmC  
?()E5 4y  
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： wKeSPs{x  
enableservice('AutomationServer', true) qU /W
g  
    enableservice('AutomationServer') hz>yv@1  
\|b1s @c8  
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。 2=Vkjh-

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： %'D:bi5  
1. 在FRED脚本编辑界面找到参考. )=SYJ-ta<  
2. 找到Matlab Automation Server Type Library :a^,Ei-&  
    3. 将名字改为MLAPP rwV u?W

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。 h>`'\qy

现在将脚本代码公布如下，此脚本执行如下几个步骤： NiJ?no  
1. 创建Matlab服务器。 *Tlws  
2. 移动探测面对于前一聚焦面的位置。 6lH>600]u  
3. 在探测面追迹光线 V=8{CmqT  
4. 在探测面计算照度 X G@>1/  
5. 使用PutWorkspaceData发送照度数据到Matlab *M**h-p2'  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 A)`fD %+  
7. 用Matlab画出照度数据 Ms$7E  
8. 在Matlab计算照度平均值 #dn%KMo2r  
9. 返回数据到FRED中 kdueQ(\
