    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。 z1F9$ ^  
    }/20%fP  
    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： DlDB=N0@S  
    enableservice('AutomationServer', true) .N5'.3  
        enableservice('AutomationServer') P*0f~eu  
    JfMJF[Mb  
    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。 C5Xof|#p|

    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： 1YFeVMc  
    1. 在FRED脚本编辑界面找到参考. ]3}feU+  
    2. 找到Matlab Automation Server Type Library ~]&B >q  
        3. 将名字改为MLAPP @d&g/ccMxd

    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。 sc%dh?m7
