    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。 ]y/:#^M+  
    G"(!5+DLy  
    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: -u(#V#}OV?  
    enableservice('AutomationServer', true) [DviN  
    enableservice('AutomationServer') mD:!"h/  
    xMu6PM<l  
    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 b(F`$N@7C  
    [Pl$=[+  
    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: K>U &jH  
    1. 在FRED脚本编辑界面找到参考. p_D)=Ef|&  
    2. 找到Matlab Automation Server Type Library od>.5{o  
    3. 将名字改为MLAPP 4ai3@f5  
    p_( NLJ%  
    r0,}f\  
    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。 G}x^PJJt

    6. 使用PutFullMatrix发送标量场数据到Matlab中 (<t)5?@%  
    7. 用Matlab画出照度数据 V3S`8VI  
    8. 在Matlab计算照度平均值 G!uxpZ
