[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。 HnOF_Twq

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： 2{U4wTu  
enableservice('AutomationServer', true) ~PoGuj2wA  
enableservice('AutomationServer') 1$Eiv8xd  
]^ RgzK  
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。 <JKPtF2b

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： RKjA`cJ  
1. 在FRED脚本编辑界面找到参考. 55,vmDd  
2. 找到Matlab Automation Server Type Library EEkO[J[=  
3. 将名字改为MLAPP x;b'y4kH

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。 >fb*X'Zi%

现在将脚本代码公布如下，此脚本执行如下几个步骤： }>tUkXlhJ<  
1. 创建Matlab服务器。 #p_ ~L4iW  
2. 移动探测面对于前一聚焦面的位置。 751\K`L  
3. 在探测面追迹光线 2V~Yb1P  
4. 在探测面计算照度 xX|-5cM;  
5. 使用PutWorkspaceData发送照度数据到Matlab yTZbJx?m  
6. 使用PutFullMatrix发送标量场数据到Matlab中 [q(7Jv  
7. 用Matlab画出照度数据 !PQ@"L)p  
8. 在Matlab计算照度平均值 ?np`RA  
9. 返回数据到FRED中 PDGh\Y[AK,
