[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。 Q3& ?28  
Zs t)S(  
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： 8J&9}@y  
enableservice('AutomationServer', true) x1`w{5;C 2  
enableservice('AutomationServer') q&[G^9  
2k=|p@V n~  
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。 3/usgw1

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： y`$qcEw  
1. 在FRED脚本编辑界面找到参考. {q$U\y%Rq  
2. 找到Matlab Automation Server Type Library Q)4[zStR#  
3. 将名字改为MLAPP NUb$PT

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。 zqU$V~5;rG

1. 创建Matlab服务器。 Ff0V6j)ji  
2. 移动探测面对于前一聚焦面的位置。 X ]&`"Z]  
3. 在探测面追迹光线 p`&{NR3+  
4. 在探测面计算照度 ueU"v'h\  
5. 使用PutWorkspaceData发送照度数据到Matlab C$q-WoTM(  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ik?IC$*n3i  
7. 用Matlab画出照度数据 0=7Ud<  
8. 在Matlab计算照度平均值 (&)uWjq `  
9. 返回数据到FRED中 a'-xCV|^
