[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。 e" f/  
r0)X]l7  
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： #;6YADk2_  
enableservice('AutomationServer', true) TPrqb  
enableservice('AutomationServer') ZV
j/lOP X  
J!,<NlP0K  
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。 C-abc+/  
%P2GQS-N  
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： ;V~[kF=t0  
1. 在FRED脚本编辑界面找到参考. @e_ bG
@  
2. 找到Matlab Automation Server Type Library Mg0[PbS  
3. 将名字改为MLAPP E1'HdOh&z

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。 E}d@0C:

现在将脚本代码公布如下，此脚本执行如下几个步骤： tB_GEt2M  
1. 创建Matlab服务器。 EencMi7J  
2. 移动探测面对于前一聚焦面的位置。 P"LbWZ6Nj  
3. 在探测面追迹光线 Uv~r]P)  
4. 在探测面计算照度 5 #)5Z8`X  
5. 使用PutWorkspaceData发送照度数据到Matlab K"O+`2$  
6. 使用PutFullMatrix发送标量场数据到Matlab中 0?KY

7. 用Matlab画出照度数据 0w

8. 在Matlab计算照度平均值 ^#T@NN0T  
9. 返回数据到FRED中 #MbkU])
