    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。 YO,GZD`-o  
    Q'A->I<;_s  
    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: -C8awtbC  
    enableservice('AutomationServer', true) gl!3pTC  
        enableservice('AutomationServer') .pdgRjlSn  
    0j_!)B  
    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 jXW71$B

    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: \lY26'  
    1. 在FRED脚本编辑界面找到参考. _FVIN;!  
    2. 找到Matlab Automation Server Type Library i, )kI  
        3. 将名字改为MLAPP 7 'f>  
         L1D%vu`  
         l|uN-{ w  
    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。 qY0Ic5wCY

    3. 在探测面追迹光线 *sw$OnVb  
    4. 在探测面计算照度 XDI@ mQmzB  
    5. 使用PutWorkspaceData发送照度数据到Matlab Fe/*U4xU  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ;XTP^W!6f  
    7. 用Matlab画出照度数据 Pd@?(WQ  
    8. 在Matlab计算照度平均值 zCco/]h
