[推荐]FRED案例-FRED如何调用Matlab [复制链接]

DoNN
;^H  
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。 Qe0?n  
%(S!/(LWW  
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： zjTCq; G  
enableservice('AutomationServer', true) )xL_jSyh  
    enableservice('AutomationServer') _aU :[v*!  
Y=i_2R2e2  
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。 iA|n\a~ny,

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： g*-}9~  
1. 在FRED脚本编辑界面找到参考. %EYh*g{G  
2. 找到Matlab Automation Server Type Library 8.&P4u i  
    3. 将名字改为MLAPP jgqeDl\=+

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。 m2l0`l~T8

1. 创建Matlab服务器。 J[UTn'M8]  
2. 移动探测面对于前一聚焦面的位置。 [B^V{nUBc  
3. 在探测面追迹光线 3*F|`js"  
4. 在探测面计算照度 (SCZ.G(>  
5. 使用PutWorkspaceData发送照度数据到Matlab 4<- E0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {qm5H7sL  
7. 用Matlab画出照度数据 djn<Oc`  
8. 在Matlab计算照度平均值 7H)tF

9. 返回数据到FRED中 UZL-mF:)&
