    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。 i:C.8hmAE  
    X'YfjbGo  
    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: d,zp `S  
    enableservice('AutomationServer', true) .UNF~}^H  
    enableservice('AutomationServer') eLCdAr  
    mk#>Dpy?  
    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 -kWO2

    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: ~C%2t{"  
    1. 在FRED脚本编辑界面找到参考. d1UVvyH  
    2. 找到Matlab Automation Server Type Library or?0PEx\  
    3. 将名字改为MLAPP >`<Ued

    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。 ^RYn8I
