    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。 f9TV%fG?  
    G'x .NL  
    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: Yck~xt&]  
    enableservice('AutomationServer', true) g4&jo_3:p  
    enableservice('AutomationServer') wJG$c-(\0  
    u&]vd /  
    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 K`k'}(vj

    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: SH8/0g?  
    1. 在FRED脚本编辑界面找到参考. bAF )Bli  
    2. 找到Matlab Automation Server Type Library .px:e)iW  
    3. 将名字改为MLAPP ~]uZy=P? 5

    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。 RT*5d;l0
