    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。 s9kTuhoK  
    LVWxd}0  
    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: X)Ocn`|  
    enableservice('AutomationServer', true) Qvs(Rt3?y  
    enableservice('AutomationServer') 14;Av{Xt  
    "rf\' 9=  
    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 Y~x`6

    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: ,Zr  YJ<  
    1. 在FRED脚本编辑界面找到参考. v.]'%+::#  
    2. 找到Matlab Automation Server Type Library { <~s&EPd  
    3. 将名字改为MLAPP 0sY#MHPT&

    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。 ^M"HSewo
