    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。 4DXbeQs:  
    OfsP5*d  
    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: ."K>h3(&V  
    enableservice('AutomationServer', true) 'X~tt#T  
    enableservice('AutomationServer') _Fb}zPU!  
    _MBa&XEM  
    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 NOz3_k

    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: Fc[KIG3@  
    1. 在FRED脚本编辑界面找到参考. yIw}n67  
    2. 找到Matlab Automation Server Type Library > =>/~dIb  
    3. 将名字改为MLAPP ;rh.6Dl

    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。 iP/v "g"g
