[分享]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。 1SQ3-WUs  
;Zcswt8]u  
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： H`XUJh  
enableservice('AutomationServer', true) >jDDQ@  
enableservice('AutomationServer') ch*8B(:  
kP=eW_0D  
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。 P1.[

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-RjMxX4>  
1. 在FRED脚本编辑界面找到参考. %Bj\W'V&p  
2. 找到Matlab Automation Server Type Library u74[>^  
3. 将名字改为MLAPP Q^P}\wb>

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。 v4!VrI

现在将脚本代码公布如下，此脚本执行如下几个步骤：  C#.->\  
1. 创建Matlab服务器。 ~p6 V,Q  
2. 移动探测面对于前一聚焦面的位置。 %_H<:uGO%  
3. 在探测面追迹光线 F@D`N0Pte  
4. 在探测面计算照度 +zqn<<9  
5. 使用PutWorkspaceData发送照度数据到Matlab ~f2z]JLr:  
6. 使用PutFullMatrix发送标量场数据到Matlab中 V5@:#BIs  
7. 用Matlab画出照度数据 ZuzEg*lb  
8. 在Matlab计算照度平均值 RXMISt3+{y  
9. 返回数据到FRED中 Gm&Za,4%4
