    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。 snK$? 9vh  
    kOmTji7  
    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: $pyM<:*L&<  
    enableservice('AutomationServer', true) - /]ro8V$  
        enableservice('AutomationServer') 7<<pP  
    8$io^n\i  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 mVcpYyD|k  
    V<$g^Vb  
    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: rW0# 6  
    1. 在FRED脚本编辑界面找到参考. 1Thr74M  
    2. 找到Matlab Automation Server Type Library (wdE@/V  
        3. 将名字改为MLAPP F42r]k  
         Z,M?!vK  
         <UQaRI[55  
    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。 WZ"NG|

    3. 在探测面追迹光线 )mz [2Sfg  
    4. 在探测面计算照度 b8P/9D7K?  
    5. 使用PutWorkspaceData发送照度数据到Matlab zW,m3~XX:  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 1mm/Ssw:C  
    7. 用Matlab画出照度数据 0(VH8@h`O  
    8. 在Matlab计算照度平均值 `C%,Nj  
    9. 返回数据到FRED中 %<6oKE
