[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。 fk*(8@u>  
KsDS!O  
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： '%$Vmf)=  
enableservice('AutomationServer', true) r@G*Fx8Z  
enableservice('AutomationServer') F^,:p.ihm<  
g*k)
ws  
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。 Tigw+2

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： ax@H^Gj@2  
1. 在FRED脚本编辑界面找到参考. X[Y0r  
2. 找到Matlab Automation Server Type Library ]n^iG7aB?  
3. 将名字改为MLAPP y

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。 KEAXDF&#

现在将脚本代码公布如下，此脚本执行如下几个步骤： qqDg2,Yb  
1. 创建Matlab服务器。 3,PR6a,b'  
2. 移动探测面对于前一聚焦面的位置。 @SfQbM##%  
3. 在探测面追迹光线 0`/G(ukO  
4. 在探测面计算照度 p fc6;K:d  
5. 使用PutWorkspaceData发送照度数据到Matlab fWHvVyQ.  
6. 使用PutFullMatrix发送标量场数据到Matlab中 d$IROZK-D  
7. 用Matlab画出照度数据 %;`Kd}CO  
8. 在Matlab计算照度平均值 ljFq;!I5  
9. 返回数据到FRED中 v l"8Oi*r^
