[分享]FRED如何调用Matlab [复制链接]

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。 ?|W3RK;  
JnK<:]LcK  
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： QH(&Cu,  
enableservice('AutomationServer', true) ~//9Nz~;3  
enableservice('AutomationServer') >_yL@^  
-kLBq:
M  
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。 /Ls|'2J<$

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： $aJay]F  
1. 在FRED脚本编辑界面找到参考. ff.k1%wr^  
2. 找到Matlab Automation Server Type Library Q34u>VkdQI  
3. 将名字改为MLAPP  d6tLCQ  
m-Jy 4f#

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。 iEtR<R>=

现在将脚本代码公布如下，此脚本执行如下几个步骤： \o
s"w "  
1. 创建Matlab服务器。 r7R'beiH  
2. 移动探测面对于前一聚焦面的位置。 4_QfM}Fyp  
3. 在探测面追迹光线 dE,E,tv  
4. 在探测面计算照度 !% W5@tN  
5. 使用PutWorkspaceData发送照度数据到Matlab @B>D>B  
6. 使用PutFullMatrix发送标量场数据到Matlab中 iU 6,B  
7. 用Matlab画出照度数据 1DcBF@3sWG  
8. 在Matlab计算照度平均值 X+A@//,7  
9. 返回数据到FRED中 tUU
