    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。 n?*r,)'  
    F-Bj  
    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: b3Q k;yz  
    enableservice('AutomationServer', true) \03ZE^H  
        enableservice('AutomationServer') |u]IOw&1  
    *vzEfmN:d  
    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 + w/B3 b  
    3~1Gts  
    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: 8]D0)  
    1. 在FRED脚本编辑界面找到参考. 055C1RV%  
    2. 找到Matlab Automation Server Type Library .$fSWlM;  
        3. 将名字改为MLAPP {2k]$|  
         X0Wx\xDg[  
         Zc'^iDAY  
    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。 =0a z5td

    3. 在探测面追迹光线 bYO['ORr @  
    4. 在探测面计算照度 @C%6Wo4l3  
    5. 使用PutWorkspaceData发送照度数据到Matlab UA|\D]xe  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 n?;h-KKO:  
    7. 用Matlab画出照度数据 Lt ^*L% x
