    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。 QN4{xf:}S  
    Mh =yIx</  
    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: Z\YCjs%  
    enableservice('AutomationServer', true) =3h?!$#?  
    enableservice('AutomationServer') q8m{zSr  
    _4#Mdnh}[  
    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 #EG W76 f  
    ABx< Ep6  
    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: V 4#bW  
    1. 在FRED脚本编辑界面找到参考. ^Z |WD!>`  
    2. 找到Matlab Automation Server Type Library 1bz%O2U-(  
    3. 将名字改为MLAPP *VUD!`F  
    {PGiNY%q  
    }1xD*[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。 lU\v8!Ji

    5. 使用PutWorkspaceData发送照度数据到Matlab [ML|, kq!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ts:YJAu+F  
    7. 用Matlab画出照度数据 qWdob>u  
    8. 在Matlab计算照度平均值 3(oB[9]s
