    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。 +8~S28"Wg3  
    ZI5UQH/  
    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： zis-}K<   
    enableservice('AutomationServer', true) ,x_g|J _Y  
        enableservice('AutomationServer') bi,%QZZ  
    & ??)gMM[  
    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。 `pLp+#1 `R

    1. 在FRED脚本编辑界面找到参考. M>0~Ek%3

    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。 >;HXH^q
