[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。  |tVWmm^m

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： )h>H}wDs  
enableservice('AutomationServer', true) FQp@/H^  
enableservice('AutomationServer') 5k]xi)%  
iFBH;O_~  
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。 S`?L\R.:

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： <^v-y)%N:A  
1. 在FRED脚本编辑界面找到参考. 9~Ve}NB#z&  
2. 找到Matlab Automation Server Type Library P"k`h=>!4  
3. 将名字改为MLAPP Ao}J

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。 T:?01?m

现在将脚本代码公布如下，此脚本执行如下几个步骤： 4w<4\zT_U}  
1. 创建Matlab服务器。 j7u\.xu9  
2. 移动探测面对于前一聚焦面的位置。 QgB%\mO=  
3. 在探测面追迹光线 XxeyGs^%9  
4. 在探测面计算照度 }g]O_fN7

5. 使用PutWorkspaceData发送照度数据到Matlab Y[p  
6. 使用PutFullMatrix发送标量场数据到Matlab中 L2P#5

7. 用Matlab画出照度数据 y%NZ(Y,v  
8. 在Matlab计算照度平均值 \-eDNwJ:#@  
9. 返回数据到FRED中 PZB_6!}2[F
