    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。 IWuR=I$t  
    AEOo]b*&d  
    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: 2vu"PeU9  
    enableservice('AutomationServer', true) pbR84g^p.S  
    enableservice('AutomationServer') OUnt?[U\  
    Lt|k}p@]  
    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 K (Z d-U  
    ZMy7z|  
    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: Wi hQj  
    1. 在FRED脚本编辑界面找到参考. 2EycFjO  
    2. 找到Matlab Automation Server Type Library Qh%7RGh_  
    3. 将名字改为MLAPP < yE(p  
    .nKyB'uV  
    Y'%sA~g  
    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。 }!lLA4XRr

    3. 在探测面追迹光线 Rfeiv  
    4. 在探测面计算照度 ) m%ghpX  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6./h0kD`  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 u}qfwVX Z  
    7. 用Matlab画出照度数据 Z\6azhbI}  
    8. 在Matlab计算照度平均值 $9M>B<]
