    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 z]H=  
    oOAkwc%)b  
    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: S#HeOPRL  
    enableservice('AutomationServer', true) :F#^Q%-IS  
        enableservice('AutomationServer') h(J$-SUs  
    B!8X?8D  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 m,62'  
    V"2 G  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 05\0g9  
    1. 在FRED脚本编辑界面找到参考. #w\x-i|  
    2. 找到Matlab Automation Server Type Library f&$;iE  
        3. 将名字改为MLAPP j!oX\Y-:&

    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。 &2[Xu4*
