[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。 (<:rKp  
:b3lJ-dB  
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： fSQ3 :o  
enableservice('AutomationServer', true) |WwFE|<  
enableservice('AutomationServer') U K]{]-  
uN?O*h/(  
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。 8d*<Aki?;

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： v2uS6  
1. 在FRED脚本编辑界面找到参考. `QyALcO  
2. 找到Matlab Automation Server Type Library 7`'fUhB!  
3. 将名字改为MLAPP K:mL%o2J

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。 .WPR}v,.Z

现在将脚本代码公布如下，此脚本执行如下几个步骤： W;AWO0+  
1. 创建Matlab服务器。 AB|VO4-?  
2. 移动探测面对于前一聚焦面的位置。 A%2M]];%X  
3. 在探测面追迹光线 fylA0{  
4. 在探测面计算照度 2KNKdV3NK  
5. 使用PutWorkspaceData发送照度数据到Matlab *U^\Mwp  
6. 使用PutFullMatrix发送标量场数据到Matlab中 `]
 dx%  
7. 用Matlab画出照度数据 OTjryJ^  
8. 在Matlab计算照度平均值 ,I:m*.q  
9. 返回数据到FRED中 @Y<ZT;J
