[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。 Om1z  
~IWi@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： bL[PNUG  
enableservice('AutomationServer', true) R
&alq  
enableservice('AutomationServer') <s7{6n')  
I] "$h]T  
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。 1)PR]s:-m@

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：  #b"IX`5  
1. 在FRED脚本编辑界面找到参考. R$3JbR.  
2. 找到Matlab Automation Server Type Library *HXq`B  
3. 将名字改为MLAPP Q)}\

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。 q}1$OsM

现在将脚本代码公布如下，此脚本执行如下几个步骤： [qI*]  
1. 创建Matlab服务器。 V_1
#7  
2. 移动探测面对于前一聚焦面的位置。 qlxW@|  
3. 在探测面追迹光线 uHIWbF<0oo  
4. 在探测面计算照度 D8#q.OR]  
5. 使用PutWorkspaceData发送照度数据到Matlab =!c+|X
`  
6. 使用PutFullMatrix发送标量场数据到Matlab中 0*"j:V  
7. 用Matlab画出照度数据 0l6

8. 在Matlab计算照度平均值 cU6#^PFu  
9. 返回数据到FRED中 [uY2Nh
