[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#Rb8&G)b  
Q k}RcP  
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： VIdKe&,  
enableservice('AutomationServer', true) |P]W#~Y-  
enableservice('AutomationServer') C<C$df  
5e.aTW;U  
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。 ]}lt^

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： 1s(T#jh  
1. 在FRED脚本编辑界面找到参考. YA,~qT|  
2. 找到Matlab Automation Server Type Library LUD.  
3. 将名字改为MLAPP SI~jM:S}

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。 'y;Kj

现在将脚本代码公布如下，此脚本执行如下几个步骤： T+nID@"36  
1. 创建Matlab服务器。 I3.. Yk%7  
2. 移动探测面对于前一聚焦面的位置。 aGC3&c[Wx  
3. 在探测面追迹光线 60^j<O  
4. 在探测面计算照度 
%<-OdyM  
5. 使用PutWorkspaceData发送照度数据到Matlab R`@T<ob)  
6. 使用PutFullMatrix发送标量场数据到Matlab中
=_pSfKR;  
7. 用Matlab画出照度数据 5?;<^J  
8. 在Matlab计算照度平均值 GGEM&0*  
9. 返回数据到FRED中 GIzB1cl:
