[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。 3z5w}qN]M  
a$-:F$z  
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： zI1-l9 o  
enableservice('AutomationServer', true) Y_S>S(0  
enableservice('AutomationServer') AT$eTZ]M  
!A@Ft}
FB  
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。 @'XxMO[Z!<

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： lM/)<I\8  
1. 在FRED脚本编辑界面找到参考. b9FfDDOq"  
2. 找到Matlab Automation Server Type Library u6tD5Y  
3. 将名字改为MLAPP L!2BE[~  
/-J12O  
zPWJ=T@N  
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。 k?[|8H~2C

现在将脚本代码公布如下，此脚本执行如下几个步骤： =\uQGH  
1. 创建Matlab服务器。 OZ,%T9vP  
2. 移动探测面对于前一聚焦面的位置。 \l$gcFXb  
3. 在探测面追迹光线 5ctH=t0  
4. 在探测面计算照度 [3&Y* W  
5. 使用PutWorkspaceData发送照度数据到Matlab LNm{}VJ%  
6. 使用PutFullMatrix发送标量场数据到Matlab中 YhpNeP{A  
7. 用Matlab画出照度数据 [,_4#Zz  
8. 在Matlab计算照度平均值 wl

9. 返回数据到FRED中 J^"
