    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。 x#wkODLqi  
    G8]DK3#  
    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\oU$'  
    enableservice('AutomationServer', true) V L^.7U  
    enableservice('AutomationServer') I+qg'mo  
    qN5 ru2  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 5|T[:m  
    yr4j  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 0Dx,)C  
    1. 在FRED脚本编辑界面找到参考. Ino$N|G[  
    2. 找到Matlab Automation Server Type Library +I>u${sVx*  
    3. 将名字改为MLAPP ejr9e@D^  
    M%*D}s-QE  
    B=0U^wL  
    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。 X# 625h

    4. 在探测面计算照度 E_fH,YJ?9  
    5. 使用PutWorkspaceData发送照度数据到Matlab tl:V8sYTP  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *w H.]$  
    7. 用Matlab画出照度数据 (d> M/x?W  
    8. 在Matlab计算照度平均值 6Kl%|VrJs
