    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。 #U:|- a.>  
    v[dU UR 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： {'b;lA]0  
    enableservice('AutomationServer', true) !"^Zr]Qt+\  
        enableservice('AutomationServer') Y'U1=w~E  
    q G%Y& P  
    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。 4H{t6t@-:

    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： yE}\4_0I/  
    1. 在FRED脚本编辑界面找到参考. a?[[F{X9^  
    2. 找到Matlab Automation Server Type Library ] Q5:JV  
        3. 将名字改为MLAPP 25>R^2,LiE

         U,g8:M xHK  
    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。 '=dQ$fs
