[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。 xc HG5bg|  
D@cv{ _M/  
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： V?*\ISB`}  
enableservice('AutomationServer', true) RTgR>qI&)  
enableservice('AutomationServer') }>|M6.n "  
V#Px  
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。 #cRw0bn:  
Vif0z*\e{  
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： WE hDep:  
1. 在FRED脚本编辑界面找到参考. Zss `##  
2. 找到Matlab Automation Server Type Library 2unaK<1s  
3. 将名字改为MLAPP W]t!I}yPR

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。 8<VO>WA>E

现在将脚本代码公布如下，此脚本执行如下几个步骤： A* =r~T5B  
1. 创建Matlab服务器。 S-8wL%r  
2. 移动探测面对于前一聚焦面的位置。 &%ZiI@O-  
3. 在探测面追迹光线 FccT@,.F  
4. 在探测面计算照度 @4'bI)  
5. 使用PutWorkspaceData发送照度数据到Matlab !p4y@U{  
6. 使用PutFullMatrix发送标量场数据到Matlab中 jBTXs5q  
7. 用Matlab画出照度数据 u9:+^F+  
8. 在Matlab计算照度平均值 Pa{)@xT  
9. 返回数据到FRED中 oBm^RHTZ
