[技术]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。 V4V`0I  
+a.2\Qt2A  
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： yO%^[c?  
enableservice('AutomationServer', true) $J4\jIipL  
enableservice('AutomationServer') oqF?9<Vgc,  
p]RQ-0  
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。 U,i_}O3Q

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： YXWDbr:JX  
1. 在FRED脚本编辑界面找到参考. 2.%)OC!q&5  
2. 找到Matlab Automation Server Type Library >B0AJW/u  
3. 将名字改为MLAPP D8L5t<^1R

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。 ~@c<5 -`{

现在将脚本代码公布如下，此脚本执行如下几个步骤： C7{VByxJ  
1. 创建Matlab服务器。 c46-8z$  
2. 移动探测面对于前一聚焦面的位置。 >(a35 b$  
3. 在探测面追迹光线 ~_EDJp1J  
4. 在探测面计算照度 s;TB(M~i[  
5. 使用PutWorkspaceData发送照度数据到Matlab gf8o~vKX$G  
6. 使用PutFullMatrix发送标量场数据到Matlab中 vGv<WEE  
7. 用Matlab画出照度数据 G"FO%3&|  
8. 在Matlab计算照度平均值 $t%IJT  
9. 返回数据到FRED中 [M[#f&=Z
