[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。 Zor Q2>  
"o<&3c4  
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： (m=F  
enableservice('AutomationServer', true) mzTM&@  
enableservice('AutomationServer') 0&2&F=fOa<  
mm
Ee@-lE  
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。 /6p7k

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： $60]R

1. 在FRED脚本编辑界面找到参考. d^XRkB:h  
2. 找到Matlab Automation Server Type Library |JCn=v@  
3. 将名字改为MLAPP U9q6m3#$

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。 y1Yrf,E m=

现在将脚本代码公布如下，此脚本执行如下几个步骤： 9 N@N U:M+  
1. 创建Matlab服务器。 4iZ7BD  
2. 移动探测面对于前一聚焦面的位置。 ZRoOdo94  
3. 在探测面追迹光线 {>>Gc2UT  
4. 在探测面计算照度 (t-JGye>  
5. 使用PutWorkspaceData发送照度数据到Matlab J<7nOB}OD  
6. 使用PutFullMatrix发送标量场数据到Matlab中 'FGf#l<  
7. 用Matlab画出照度数据 5> =Ia@I   
8. 在Matlab计算照度平均值 x^6

9. 返回数据到FRED中 VXu1YxY
