FRED案例-FRED如何调用Matlab

ew8Manx  
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。 BH?fFe&J:`  
Q .cL1uHc  
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: *3!ixDX[r  
enableservice('AutomationServer', true) x*F_XE1#M  
    enableservice('AutomationServer') ' C1yqkIa`  
;8<lgZ9H<  
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。 AaJnRtBS~

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: e&XJK*Wf   
1. 在FRED脚本编辑界面找到参考. 0Y ld!L  
2. 找到Matlab Automation Server Type Library +WFa4NZ  
    3. 将名字改为MLAPP Tn\59 (  
     DUu~s,A  
     tumYZ)nW  
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。 7 [?]DyOf

现在将脚本代码公布如下,此脚本执行如下几个步骤: AU H_~SY  
1. 创建Matlab服务器。 `v1~nNoY  
2. 移动探测面对于前一聚焦面的位置。 V%!my[b  
3. 在探测面追迹光线 CKRnkTTiV  
4. 在探测面计算照度 WzO[-csy  
5. 使用PutWorkspaceData发送照度数据到Matlab [5jXYqD=vj  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 g 2&P  
7. 用Matlab画出照度数据 V']1j  
8. 在Matlab计算照度平均值 6ALUd^  
9. 返回数据到FRED中 2o9IP>#u
