    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。 >!}`%pk(  
    >Rt9xP  
    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: ~s#e,Kav"  
    enableservice('AutomationServer', true) IZ8y}2  
    enableservice('AutomationServer') =MC~GXJSNw  
    Q2eXK[?*  
    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 =OYQM<q

    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: :tM?%=Q  
    1. 在FRED脚本编辑界面找到参考. c&f y{}10  
    2. 找到Matlab Automation Server Type Library h>wcT VF  
    3. 将名字改为MLAPP <*u C

    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。 6e.v&f7(
