[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。 N;Gf,pE  
tg m{gR  
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： A~~|X  
enableservice('AutomationServer', true) -7Y'6''~W.  
enableservice('AutomationServer') y&O_Jyg<  
`A}{ I}xq  
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。 N?u2,h-  
*b7 ^s,?  
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： <?`e9o  
1. 在FRED脚本编辑界面找到参考. #ui%=ja[:~  
2. 找到Matlab Automation Server Type Library uJAB)ti2I  
3. 将名字改为MLAPP khO<Z^wi[

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。 <3]/ms

现在将脚本代码公布如下，此脚本执行如下几个步骤： f~(^|~ZT  
1. 创建Matlab服务器。 I$P7%}  
2. 移动探测面对于前一聚焦面的位置。 eC1c`@C:  
3. 在探测面追迹光线 dT-O8  
4. 在探测面计算照度 ;lPhSkD  
5. 使用PutWorkspaceData发送照度数据到Matlab  3kzGL  
6. 使用PutFullMatrix发送标量场数据到Matlab中 5'}!v  
7. 用Matlab画出照度数据 tGy%n[ \  
8. 在Matlab计算照度平均值 looPO:bo^  
9. 返回数据到FRED中 h"%,eW|^
