    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。 [8sL);pJO  
    pKM5<1J  
    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: "E><:_,\  
    enableservice('AutomationServer', true) L,QAE)S'a  
        enableservice('AutomationServer') }: W6Bo-|  
    DJF-J#  
    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 aK ly1G

    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: ?b&~(,A{  
    1. 在FRED脚本编辑界面找到参考. 4*<27  
    2. 找到Matlab Automation Server Type Library 6}vPwI  
        3. 将名字改为MLAPP :e&P's=

    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。 P]pVYX# m
