[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。 keOW{:^i  
c &HoS  
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： B}X#oA  
enableservice('AutomationServer', true) %a `dOEO  
enableservice('AutomationServer') w3>|mDA}I  
R{_IrYk  
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。 K}BX6dA

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： }^7V^W  
1. 在FRED脚本编辑界面找到参考. 3iw9jhK!W  
2. 找到Matlab Automation Server Type Library ;\+0H$  
3. 将名字改为MLAPP >gJWp@6V

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。 L:-lqag!

现在将脚本代码公布如下，此脚本执行如下几个步骤： "Ycd$`{Vgt  
1. 创建Matlab服务器。 sjm79/  
2. 移动探测面对于前一聚焦面的位置。 WKsx|a]U  
3. 在探测面追迹光线 m{c#cR  
4. 在探测面计算照度 98^6{p  
5. 使用PutWorkspaceData发送照度数据到Matlab <

6. 使用PutFullMatrix发送标量场数据到Matlab中 HU

7. 用Matlab画出照度数据 6l'y  
8. 在Matlab计算照度平均值 UI C? S  
9. 返回数据到FRED中 8 -A7
