    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。 %<0'xJ%%Q  
    rS8}(lf  
    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: H/U.Bg 4  
    enableservice('AutomationServer', true) bae;2| w  
    enableservice('AutomationServer') 6Ts[NXa  
    />n!2'!  
    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 G=/^]E  
    )G),iy  
    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: 0^vz /y1c  
    1. 在FRED脚本编辑界面找到参考. $5:I~ -mx  
    2. 找到Matlab Automation Server Type Library :s*t\09V7  
    3. 将名字改为MLAPP !bs5w_@

    X-*LA*xbN  
    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。 6UI6E)g

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ,_ TE@ ]!$  
    1. 创建Matlab服务器。 C8W_f( i~

    4. 在探测面计算照度 g/frg(KF  
    5. 使用PutWorkspaceData发送照度数据到Matlab dVg'v7G&V(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 EM(%|#  
    7. 用Matlab画出照度数据 ++n_$Qug  
    8. 在Matlab计算照度平均值 K~4bT=   
    9. 返回数据到FRED中 $*`E;}S0
