    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。 IfCqezd  
    P`"DepeD  
    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: to=##&ld<  
    enableservice('AutomationServer', true) +[[gU;U"v  
    enableservice('AutomationServer') 5c7a\J9>  
    H,~In2Z  
    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 p'}%pAY  
    }rZ=j6Z  
    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: Z+4Oa f!  
    1. 在FRED脚本编辑界面找到参考. S]g)^f'a65  
    2. 找到Matlab Automation Server Type Library L-$g& -  
    3. 将名字改为MLAPP Nq6CvDXi  
    i=QhX CM  
    ".<p R} qp  
    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。 W^Y(FUy~
