    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。 I "+|cFq.  
    |Z +E(F  
    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： 1QdB`8in  
    enableservice('AutomationServer', true) OYCFx2{  
        enableservice('AutomationServer') }j5@\c48  
    A'P}mrY  
    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。 <\#  
    :/?R9JVI  
    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： . LVOaxT  
    1. 在FRED脚本编辑界面找到参考. Y)-)NLLG;n  
    2. 找到Matlab Automation Server Type Library zz''FmedF  
        3. 将名字改为MLAPP 3  %{'Uh,

    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。 H'(o}cn7~
