[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。 '1>g=Ic0  
4A\BGD*5  
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： O,F]\  
enableservice('AutomationServer', true) no~OR Q  
enableservice('AutomationServer') 9_M H  
c,v^A+sZu  
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。 =yk Rki

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： #~bU}[{  
1. 在FRED脚本编辑界面找到参考. J8sJ~FnUj  
2. 找到Matlab Automation Server Type Library SQO>}#qm  
3. 将名字改为MLAPP LY@1@O2@

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。 `^XRrVX<

现在将脚本代码公布如下，此脚本执行如下几个步骤： ImUQ*0  
1. 创建Matlab服务器。 ?G~/{m.  
2. 移动探测面对于前一聚焦面的位置。 ZYwBw:y}y  
3. 在探测面追迹光线 p=8M0k  
4. 在探测面计算照度 jQ.>2-;H9  
5. 使用PutWorkspaceData发送照度数据到Matlab )1ZJ  
6. 使用PutFullMatrix发送标量场数据到Matlab中 @1pW!AdN  
7. 用Matlab画出照度数据 [M7iJcwt  
8. 在Matlab计算照度平均值 rQd1Ch  
9. 返回数据到FRED中 Jf%!I
