    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。 +[J/Zw0{  
    <*t4D-os  
    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: p#SY /KIw  
    enableservice('AutomationServer', true) D0mI09=GtQ  
    enableservice('AutomationServer') ,Rx{yf]k  
    w'X]M#Q><  
    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 _5MNMV LwW  
    #{9G sD  
    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: "lNzGi-H  
    1. 在FRED脚本编辑界面找到参考. 5'w^@Rs5  
    2. 找到Matlab Automation Server Type Library 'a^{=+  
    3. 将名字改为MLAPP G pbC M~x

    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。 "xAWG$b
