[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。 m;m4/z3U  
nuLxOd*n  
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： ^*+-0b;[G  
enableservice('AutomationServer', true) 6ZwFU5)QE/  
enableservice('AutomationServer') ~0ZLaiJ  
`|g*T~; kC  
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。 w@\quy:

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： O^I%Xk  
1. 在FRED脚本编辑界面找到参考. * 57y.](w  
2. 找到Matlab Automation Server Type Library cT,5xp"a

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。 2Uq4PCx!

现在将脚本代码公布如下，此脚本执行如下几个步骤： *kWrF* )J  
1. 创建Matlab服务器。 uZ7~E._  
2. 移动探测面对于前一聚焦面的位置。 ~pj/_@S@x  
3. 在探测面追迹光线 C`>|D [  
4. 在探测面计算照度 /?Fa<{  
5. 使用PutWorkspaceData发送照度数据到Matlab {Tym#  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ZsikI@?  
7. 用Matlab画出照度数据 +x"cWOg  
8. 在Matlab计算照度平均值 Lv`NS+fX  
9. 返回数据到FRED中 f;PvXq<7"
