[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。 zXvAW7  
WU{G_Fqaz  
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： ar=uDb;  
enableservice('AutomationServer', true) [1dlV/  
enableservice('AutomationServer') ,S:LhgSP  
g-meJhX%  
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。 e!ar

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： Tw`^  
1. 在FRED脚本编辑界面找到参考. a~7`;Ar  
2. 找到Matlab Automation Server Type Library uOs 8|pj,  
3. 将名字改为MLAPP EG59L~nM

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。 F%lP<4Vx

1. 创建Matlab服务器。 <:2El9l!  
2. 移动探测面对于前一聚焦面的位置。 /{d7%Et6
 
3. 在探测面追迹光线 ;a XcGa  
4. 在探测面计算照度 b(I-0<  
5. 使用PutWorkspaceData发送照度数据到Matlab c@~\ FUr  
6. 使用PutFullMatrix发送标量场数据到Matlab中 I/<aY*R4  
7. 用Matlab画出照度数据 OCa74)(  
8. 在Matlab计算照度平均值 7\rz*  
9. 返回数据到FRED中 ?^Q!=W<7
