    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。 `F)Q=  
    g8I=s7cnb  
    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: ^7cZ9/3  
    enableservice('AutomationServer', true) !sbKJ+V7  
        enableservice('AutomationServer') *&i SW~s  
    OB-2xmZW  
    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 ,VtrQb)Yf  
    k{fTq KS%h  
    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: ;a]Lxx;-  
    1. 在FRED脚本编辑界面找到参考. v\LcZt`}  
    2. 找到Matlab Automation Server Type Library }PdHR00^  
        3. 将名字改为MLAPP F.nJX ZnJ

    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。 Ib$*w)4:
