[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。 i"2[OM\j7  
/WXy!W30<  
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： yHkZInn  
enableservice('AutomationServer', true) p% ESp&  
enableservice('AutomationServer') 4&;.>{:;  
BFmYb
K  
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。 @sv==|h

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： dP[l$/  
1. 在FRED脚本编辑界面找到参考. JViglO1\  
2. 找到Matlab Automation Server Type Library 2)]C'  
3. 将名字改为MLAPP 6r"uDV #0

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。 r(N

1. 创建Matlab服务器。 9'F-D  
2. 移动探测面对于前一聚焦面的位置。 )iadu  
3. 在探测面追迹光线 qR0V\OtgY~  
4. 在探测面计算照度 6#VG,'e3  
5. 使用PutWorkspaceData发送照度数据到Matlab
